The articles “a” and “an” are used herein to refer to one or more (ie, at least one) grammatical objects of the article. By way of example, “a polymer resin” means one polymer resin or more than one polymer resin. Any ranges set forth herein are inclusive. The terms “substantially” and “about” as used throughout this specification are used to describe and explain minor variations. For example, the terms are ± 2% or less, such as ± 1% or less, such as ± 0.5% or less, ±
± 5% or less, such as 0.2% or less, ± 0.1% or less, or ± 0.05% or less.

Bulk solidified amorphous alloys, or bulk metallic glass (“BMG”), is a recently developed class of metallic materials. These alloys can be solidified and cooled at a relatively moderate rate, and they maintain an amorphous, amorphous (ie, glassy) state at room temperature. Amorphous alloys have many superior properties than their crystalline counterparts. However, if the cooling rate is not sufficiently high, crystals may form within the alloy during cooling, thus losing the benefits of the amorphous state. For example, one important challenge associated with the manufacture of bulk amorphous alloy parts is the partial crystallization of those parts, either by slow cooling or by impurities in the alloy raw material. In BMG parts, a high degree of amorphization (and conversely, a low degree of crystallinity) is desirable, so there is a need to develop a method for casting BMG parts with a controlled amount of amorphization. There is.

FIG. 1 (obtained from US Pat. No. 7,575,040) is Liquidmetal Te.
Figure 3 shows viscosity-temperature graphs of exemplary bulk solidified amorphous alloys from the VIT-001 series of the Zr--Ti--Ni--Cu--Be family produced by chemistry. It should be noted that there is no clear liquid / solid transformation for bulk solidifying amorphous metals during the formation of amorphous solids. This molten alloy becomes increasingly viscous with increasing supercooling until it approaches a solid form near the glass transition temperature. Thus, the temperature of the solidification front for the bulk solidified amorphous alloy can be near the glass transition temperature, where it actually acts as a solid to remove the quenched amorphous sheet product.

FIG. 2 (obtained from US Pat. No. 7,575,040) shows a time-temperature-transformation (TTT) cooling curve, or TTT diagram, of an exemplary bulk solidified amorphous alloy. Bulk solidified amorphous metals, like conventional metals, do not undergo liquid / solid crystallization transformations upon cooling. Instead, the highly flowable amorphous form of the metal found at high temperatures (near the “melting temperature” Tm) becomes more viscous as the temperature decreases (to near the glass transition temperature Tg) In particular, it exhibits the external physical properties of a conventional solid.

For bulk solidified amorphous metals, the “melting temperature” Tm can be defined as the thermodynamic liquid phase temperature of the corresponding crystal phase, even though there is no liquid / crystallization transformation. Under this regime, the viscosity at the melting temperature of the bulk solidified amorphous alloy can be in the range of about 0.1 poise to about 10,000 poise, and in some cases less than 0.01 poise. . This lower viscosity at the “melting temperature” results in faster and complete filling of complex parts of the shell / mold with bulk solidified amorphous metal to form BMG parts. Furthermore, the cooling rate of the molten metal to form the BMG part is the time between cooling-
The temperature profile must be such that it does not cross the nose shaped region that bounds the crystallization region in the TTT diagram of FIG. In FIG. 2, T nose is the critical crystallization temperature Tx where crystallization is most rapid and occurs on the shortest time scale.

The supercooled liquid region, i.e., the temperature region from Tg to Tx, demonstrates extreme stability against crystallization of the bulk solidified alloy. Within this temperature range, the bulk solidified alloy can exist as a highly viscous liquid. The viscosity of the bulk solidified alloy in this supercooled liquid region is from 10 ¹² Pa · s at the glass transition temperature to 10 ⁵ P at the high temperature limit of the supercooled liquid region, which is the crystallization temperature.
It can change in the range up to a · s. A liquid having such a viscosity can experience substantial plastic strain under pressure. Embodiments herein utilize the large plastic formability within this supercooled liquid region as a forming and separating method.

It is necessary to clarify Tx. Technically, the nose shaped curve shown in the TTT diagram describes Tx as a function of temperature and time. Therefore, Tx is reached when it hits this TTT curve, regardless of the trajectory followed during heating or cooling of the metal alloy. FIG.
In (b), Tx is shown as a dashed line, which is from Tm proximal to Tg proximal,
This is because x can vary.

The schematic TTT diagram of FIG. 2 shows a die casting processing method in which the time-temperature trajectory (shown as (1) as an exemplary trajectory) does not hit the TTT curve and is greater than or equal to Tm and less than Tg. During die casting, this shaping is performed at the same time as the rapid cooling to avoid the trajectory hitting the TTT curve. Time-temperature trajectory ((2), (3) as exemplary trajectories
And (shown as (4)) does not hit the TTT curve, a processing method for superplastic forming (SPF) from Tg or less to less than Tm. In SPF, amorphous BMG is reheated into the supercooled liquid region and the available processing window can be much larger than die casting, resulting in better process controllability. The SPF process does not require rapid cooling to avoid crystallization during cooling. An exemplary trajectory (2)
, (3), and (4), SPF can be performed with the highest temperature during SPF being above or below T nose and up to about Tm. In the case of avoiding hitting the TTT curve while raising the temperature of the piece of amorphous alloy, “Tg˜T
Even when heated to “m”, Tx has not been reached.

The typical differential scanning calorimeter (DSC) heating curve of bulk solidified amorphous alloys, obtained at a heating rate of 20 ° C./min, largely describes the specific trajectory across the TTT data. Temperature Tg and Tx when DSC heating ramp intersects TTT crystallization start
And finally the melting peak where the same trajectory intersects the temperature range for melting. Avoid TTT curves completely when heating bulk solidified amorphous alloys at a rapid heating rate as shown by the up-tilted portions of trajectories (2), (3), and (4) in FIG. And DSC data show a glass transition upon heating,
Tx is not shown. Another way of thinking about this is the trajectories (2), (3), and (4)
Is that it can fit anywhere within the TTT curve nose (and further above) to the temperature of the Tg line, as long as it does not hit the crystallization curve. That simply means that as the processing temperature increases, the horizontal flats in the trajectory can become much shorter.
phase

As used herein, the term “phase” can refer to what can be found in a thermodynamic phase diagram. A phase is a region of space (eg, a thermodynamic system) throughout which all physical properties of the material are essentially uniform. Examples of physical properties include density, refractive index, chemical composition, and lattice periodicity. A simple description of a phase is a region of material that is chemically uniform, physically different, and / or mechanically separable. For example, in a system consisting of ice and water in a glass jar, the ice cube is one phase, water is the second phase, and humid air above the water is the third phase. Jar glass is another separate phase. The phase may refer to a solid solution such as a solution of two components, three components, four components or more, or a compound such as an intermetallic compound.
As another example, the amorphous phase can be distinguished from the crystalline phase.
Metals, transition metals, and non-metals

The term “metal” refers to an electropositive chemical element. The term “element” as used herein generally refers to an element that can be found in the periodic table. Physically, a ground state metal atom includes a partially filled band with an empty state close to the occupied state. The term “transition metal” is the third in the periodic table that has an incomplete internal electron shell and serves as a transition link between the most electropositive and the least electropositive in a set of elements. It is one of the metal elements within the range of Group 12 to Group 12. Transition metals are characterized by multiple valences, colored compounds, and the ability to form stable complex ions. The term “nonmetal” refers to a chemical element that does not have the ability to lose electrons and form a cation.

Depending on the application, any suitable non-metallic elements, or combinations thereof, can be used. The alloy (or “alloy composition”) has at least 2, at least 3, at least 4
It may include a plurality of non-metallic elements such as one or more non-metallic elements. Nonmetallic elements are the first in the periodic table.
It can be any element found within Group 3 to Group 17. For example, the nonmetallic elements are F, Cl, Br, I, At, O, S, Se, Te, Po, N, P, As, Sb, B
Any one of i, C, Si, Ge, Sn, Pb, and B can be used.
In some cases, the non-metallic element may also be a specific metalloid within group 13 to group 17 (eg, B, S
i, Ge, As, Sb, Te, and Po). In one embodiment, the non-metallic element can include B, Si, C, P, or a combination thereof. Thus, for example, the alloy can include borides or carbides, or both.

Transition metal elements are scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, yttrium, zirconium, niobium, molybdenum, technetium, ruthenium, rhodium, palladium, silver, cadmium, hafnium, tantalum, tungsten , Rhenium, osmium, iridium, platinum, gold, mercury, rutherfordium, dobnium, seaborgium, bolium, hassium, mitonium, ununnilium, ununnium, and ununbium. In one embodiment, the transition metal element-containing BMG is Sc, Y, La, Ac, Ti, Zr, Hf, V
Nb, Ta, Cr, Mo, W, Mn, Tc, Re, Fe, Ru, Os, Co, Rh, I
at least one of r, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, and Hg
Can have one. Depending on the application, any suitable transition metal element, or combinations thereof, can be used. The alloy composition may include a plurality of transition metal elements, such as at least 2, at least 3, at least 4 or more transition metal elements.

An alloy or alloy “sample” or “specimen” alloy described herein may have any shape or size. For example, the alloy can have a particulate shape, which can have a shape such as a sphere, ellipse, wire, rod, sheet, flake, or irregular shape. The microparticles can have any size. For example, the microparticles can be about 5 micrometers to about 80 micrometers, such as about 10 micrometers to about 60 micrometers, such as about 15 micrometers to about 50 micrometers, such as about 15 micrometers to about 45 micrometers, etc. It may have an average diameter of about 1 micrometer to about 100 micrometers, such as about 25 micrometers to about 35 micrometers, such as about 20 micrometers to about 40 micrometers. For example, in one embodiment, the average diameter of the microparticles is about 25.
Micrometer to about 44 micrometers. In some embodiments, smaller particles, such as those in the nanometer range, or larger particles, such as those larger than 100 micrometers, can be used.

The alloy sample or specimen can also be of much larger dimensions. For example, it can be a bulk structural component such as an ingot, a housing / casing of an electronic device, or even a part of a structural component having dimensions in the millimeter, centimeter, or meter range.
Solid solution

The term “solid solution” refers to the solid form of the solution. The term “solution” refers to a mixture of two or more substances that can be a solid, liquid, gas, or a combination thereof. This mixture can be homogeneous or heterogeneous. The term “mixture” is a composition of two or more substances that can be combined with each other and generally separated. In general, the two or more substances are not combined with each other.
alloy

In some embodiments, the alloy compositions described herein can be fully alloyed. In one embodiment, an “alloy” refers to a homogenous mixture or solid solution of two or more metals in which one atom replaces another atom or occupies an interstitial position between atoms. For example, brass is an alloy of zinc and copper. An alloy can refer to a partial or complete solid solution of one or more elements in a metal matrix, such as one or more compounds in the metal matrix, as opposed to a composite material. The term alloy herein may refer to both a fully solid solution alloy that may exhibit a single solid phase microstructure and a partial solution that may exhibit two or more phases. The alloy compositions described herein can refer to those comprising an alloy or those comprising an alloy-containing composite material.

Thus, a fully alloyed alloy can have a homogeneous distribution of its constituents, whether in solid solution phase, compound phase, or both. As used herein, the term “fully alloyed” can describe slight variations within tolerances. For example, the term is
At least 99.5%, such as at least 95% alloyed, such as at least 99% alloyed
May refer to at least 90% alloying, such as at least 99.9% alloying. Percentages herein can refer to either volume percentages or weight percentages, depending on the context. These percentages can be balanced by impurities that can be in terms of compositions or phases that are not part of the alloy.
Amorphous or amorphous solid

An “amorphous” or “amorphous solid” is a solid that lacks the lattice periodicity characteristic of crystals. As used herein, “amorphous solid” includes “glass”, which is an amorphous solid that softens and transforms into a liquid state upon heating through the glass transition.
In general, amorphous materials lack the long-range order characteristic of crystals, but these amorphous materials can possess some short-range order on the atomic length scale due to the nature of chemical bonds. A distinction between an amorphous solid and a crystalline solid can be made based on lattice periodicity determined by structural property evaluation techniques such as X-ray diffraction and transmission electron microscopy.

The terms “order” and “disorder” indicate the presence or absence of any symmetry or correlation within a multiparticulate system. The terms “long-range order” and “short-range order” distinguish order within a material based on a length scale.

The most rigorous form of order in a solid is lattice periodicity, and a specific pattern (atom arrangement in a unit cell) is repeated many times to form a translational uniform space filling of the space. This lattice periodicity is a defining characteristic of crystals. The possible symmetries are grouped into 14 Bravey lattices and 230 space groups.

Lattice periodicity suggests long-range order. If only one unit cell is known, its translational symmetry makes it possible to accurately predict all atomic arrangements at an arbitrary distance. The converse is generally true, except in the case of, for example, quasicrystals that have a completely deterministic filling but do not possess lattice periodicity.

Long-range order characterizes a physical system in which remote parts of the same sample exhibit correlated behavior. This long-range order can be expressed as a correlation function, that is, the next spin-spin correlation function.

In the above function, s is a spin quantum number and x is a distance function in a specific system. This function is equal to the identity element when x = x ′ and decreases as the distance | x−x ′ | increases. Typically, this function decays exponentially to zero over long distances and the system is considered disordered. However, if this correlation function decays to a constant value with a large | x−x ′ |, it can be stated that the system possesses long-range order. This function is
If it decays to zero with a power of distance, it can be called quasi-long-range order. Note that what constitutes a large value of | x−x ′ | is relative.

A system can be extended to exhibit a quenching disorder, such as a spin glass, if some parameters that define its behavior are random variables that do not evolve over time (ie, they are quenched or frozen). it can. This quenching disorder is the opposite of the annealing disorder in which the random variable itself can develop. Embodiments herein include systems that include a quenching disorder.

The alloys described herein can be crystalline, partially crystalline, amorphous, or substantially amorphous. For example, an alloy sample / specimen can include at least some degree of crystallinity, and the grains / crystals have a size in the nanometer and / or micrometer range. Alternatively, the alloy can be substantially amorphous, such as completely amorphous. In one embodiment, the alloy composition is substantially crystalline, such as fully crystalline, and at least not substantially amorphous.

In one embodiment, the presence of one or more crystals in another amorphous alloy can be interpreted as a “crystalline phase” in that alloy. The degree of crystallinity of an alloy (or in some embodiments, “crystallinity” for short) can refer to the amount of crystalline phase present in the alloy. The degree can refer, for example, to the fraction of crystals present in the alloy. This fraction can refer to a volume fraction or a weight fraction, depending on the context. A measure of how “amorphous” an amorphous alloy can be is the degree of amorphization.
The degree of amorphization can be measured from the viewpoint of the degree of crystallinity. For example, in one embodiment, an alloy having a low degree of crystallinity can be described as having a high degree of amorphousness. In one embodiment, for example, an alloy having 60 volume percent crystalline phase is
It can have 40 volume% amorphous phase.
Amorphous alloy or amorphous metal

“Amorphous alloy” means an amorphous content greater than 50% by volume, preferably greater than 90% by volume, more preferably greater than 95% by volume, most preferably greater than 99% by volume to almost 100% by volume. % Is an alloy with an amorphous content. As noted above, it should be noted that alloys with a high degree of amorphization have an equally low degree of crystallinity. An “amorphous metal” is an amorphous metal material having a disordered atomic scale structure. In contrast to most metals, which are crystalline and thus have a highly ordered atomic arrangement, amorphous alloys are amorphous. The material in which such a disordered structure is created directly from the liquid state during cooling may be referred to as “glass”. Thus, amorphous metals are commonly referred to as “metallic glass” or “glass metal”. In one embodiment, bulk metallic glass (“BMG”) can refer to an alloy whose microstructure is at least partially amorphous. However, in addition to extreme rapid cooling, there are several ways to create amorphous metals, including physical vapor deposition, solid phase reaction, ion irradiation, melt spinning, and mechanical alloying. Amorphous alloys can be a single class of materials regardless of how they are prepared.

Amorphous metal can be produced through various quenching methods. For example, amorphous metal can be created by sputtering molten metal onto a rotating metal disk. A quench of about several million degrees per second can be too fast for crystals to form, so that the metal is “fixed” in the glassy state. Amorphous metals / alloys are also used to enable the formation of thick layer amorphous structures, such as bulk metallic glass.
It can also be produced at a sufficiently low critical cooling rate.

The terms “bulk metallic glass” (“BMG”), bulk amorphous alloy (“BAA”),
And bulk-solidifying amorphous alloys are used interchangeably herein. These terms are
Refers to an amorphous alloy having a minimum dimension in the range of at least millimeters. For example,
The dimension is at least about 0.5 mm, such as at least about 1 mm, at least about 2 mm, at least about 4 mm, at least about 5 mm, at least about 6 mm, at least about 8 mm, at least about 10 mm, at least about 12 mm, etc. It can be. Depending on the geometry, the dimensions can refer to diameter, radius, thickness, width, length, etc. The BMG may also be a metallic glass having at least one dimension in the centimeter range, such as at least about 1.0 cm, such as at least about 2.0 cm, such as at least about 5.0 cm, such as at least about 10.0 cm. You can also. In some embodiments, the BMG may have at least one dimension in the range of at least meters. BM
G can take on any of the shapes or forms described above associated with metallic glass. Thus, the BMG described herein may differ from thin films made by conventional deposition techniques in one important aspect in some embodiments, the former B
MG can be much larger in size than the latter thin film.

The amorphous metal can be an alloy rather than a pure metal. This alloy can contain atoms of significantly different sizes, resulting in a low free volume in the molten state (and therefore has a viscosity that is orders of magnitude higher than other metals and alloys). . This viscosity prevents atoms from moving sufficiently to form an ordered lattice. This material structure can provide low shrinkage during cooling and resistance to plastic deformation. This absence of grain boundaries, which in some cases is a weakness of crystalline materials, can result in better resistance to wear and corrosion, for example. In one embodiment, although technically glass, amorphous metals can also be much stronger and less brittle than oxide glasses and ceramics.

The thermal conductivity of amorphous materials can be lower than the thermal conductivity of their crystalline counterparts. To achieve the formation of an amorphous structure even during slower cooling,
Alloys with more than two components can be made to yield composite crystal units with higher potential energy and lower probability of formation. The formation of an amorphous alloy is dependent on several factors: the composition of the alloy constituents, the atomic radii of the constituents (preferably more than 12% to achieve high compaction density and low free volume). As well as the negative mixing heat of the combination of components that prevents crystal nucleation and extends the time that the molten metal remains supercooled. However, since the formation of an amorphous alloy is based on a wide variety of variables, it may be difficult to determine in advance whether the alloy composition forms an amorphous alloy.

For example, boron, silicon, phosphorus, and other glass formers and magnetic metals (iron, cobalt,
The amorphous alloy with nickel) can be magnetic with low coercivity and high electrical resistance. This high resistance results in low loss due to eddy currents when exposed to an alternating magnetic field, which is a characteristic useful as a magnetic core for a transformer, for example.

Amorphous alloys can have a variety of potentially useful properties. Specifically, amorphous alloys tend to be stronger than crystalline alloys of similar chemical composition, and they can withstand greater reversible (“elastic”) deformation than crystalline alloys. Amorphous metals derive their strength directly from their amorphous structure, which can have no defects (such as dislocations) that limit the strength of the crystalline alloy. For example, one state-of-the-art amorphous metal, known as Vitreloy ™, has a tensile strength approximately twice that of high-grade titanium. In some embodiments, the metallic glass at room temperature is not ductile and breaks suddenly when tension is applied, which is not evident in imminent failure, so in applications where reliability is important, Limit applicability of the material. Therefore, to overcome this challenge, a metal matrix composite having a metallic glass matrix containing ductile crystalline metal dendritic particles or fibers can be used. Or an element that tends to cause damage (
For example, BMG with low Ni) can be used. For example, BM without Ni
By using G, the ductility of the BMG can be improved.

Another useful property of bulk amorphous alloys is that they are intrinsic glasses, in other words they can soften and flow with heating. This allows easy processing such as injection molding as well as polymer. As a result, amorphous alloys can be used to make sports equipment, medical devices, electronic components and equipment, and thin films. Amorphous metal thin films can be deposited as protective coatings via high speed oxygen fuel technology.

The material can have an amorphous phase, a crystalline phase, or both. These amorphous and crystalline phases can have the same chemical composition and differ only in microstructure (ie, one is amorphous and the other is crystalline). The microstructure in one embodiment is 2
It refers to the structure of a material as revealed by a microscope with a magnification of 5 × or more. Alternatively, these two phases can have different chemical compositions and microstructures. For example, the composition can be partially amorphous, substantially amorphous, or fully amorphous.

As described above, the degree of amorphization (and conversely, the degree of crystallinity) can be measured by the fraction of crystals present in the alloy. The degree can refer to the volume fraction or weight fraction of the crystalline phase present in the alloy. A partially amorphous composition includes at least about 10%, such as at least about 20%, such as at least about 40%, such as at least about 60%, such as at least about 80%, such as at least about 90%. , Which can refer to a composition at least about 5% by volume of which is in an amorphous phase. The terms “substantially” and “about” are defined elsewhere in this specification. Thus, a composition that is at least substantially amorphous includes at least about 95%, such as at least about 98%, such as at least about 99%, such as at least about 99.5%.
It can refer to at least about 90% by volume of which is amorphous, such as at least about 99.8% by volume, such as at least about 99.9% by volume. In one embodiment, the substantially amorphous composition may have some accompanying small amount of crystalline phase present inside.

In one embodiment, the amorphous alloy composition can be homogeneous with respect to the amorphous phase. A substance with a uniform composition is homogeneous. This is in contrast to materials that are heterogeneous. The term “composition” refers to the chemical composition and / or microstructure in a substance. The substance is
It is homogeneous when the volume of the material is divided in half and both halves have substantially the same composition. For example, a particulate suspension is homogeneous when the volume of the particulate suspension is divided in half and both halves have substantially the same volume of particles. However, it may be possible to see individual particles under a microscope. Another example of a homogeneous material is air, where the various components in the air are equally floating, but the particles, gases, and liquids in the air can be analyzed separately or separated from the air. You can also.

A composition that is homogeneous with respect to an amorphous alloy can refer to one having an amorphous phase that is distributed substantially uniformly throughout its microstructure. In other words, the composition macroscopically comprises an amorphous alloy that is distributed substantially uniformly throughout the composition. In an alternative embodiment, the composition can be of a composite material having an amorphous phase with a non-amorphous phase therein. This non-amorphous phase can be a single crystal or multiple crystals. These crystals are spherical, elliptical, wire-like, rod-like,
It can be in the form of particulates of any shape, such as sheet, flake, or irregular shape. In one embodiment, the crystals can have a dendritic morphology. For example, an at least partially amorphous composite composition may have a crystalline phase in the form of dendrites dispersed in an amorphous phase matrix, and this dispersion may be uniform or non-uniform. In one embodiment, the amorphous phase and the crystalline phase can have the same chemical composition or different chemical compositions, and the phases can have substantially the same chemical composition. In another embodiment, the crystalline phase is B
It can be made more ductile than the MG phase.

The methods described herein may be applicable to any type of amorphous alloy. Similarly, the amorphous alloy described herein as a component of the composition or article can be of any type. This amorphous alloy is composed of Zr, Hf,
Ti, Cu, Ni, Pt, Pd, Fe, Mg, Au, La, Ag, Al, Mo, Nb, B
e elements, or combinations thereof. That is, the alloy may include any combination of these elements in its chemical formula or chemical composition. These elements can be present in various weight or volume percentages. For example, an iron “base” alloy can refer to an alloy having a significant weight percentage of iron present therein, such as at least about 50 wt%, such as at least about 40 wt%. At least about 60% by weight
At least about 20% by weight, such as at least about 80% by weight. Alternatively, in one embodiment, the percentages described above can be volume percentages instead of weight percentages. Thus, the amorphous alloy can be a zirconium base, a titanium base, a platinum base, a palladium base, a gold base, a silver base, a copper base, an iron base, a nickel base, an aluminum base, a molybdenum base, and the like. The alloy may also not include any of the above-described elements to suit a particular purpose.
For example, in some embodiments, the alloy, or a composition comprising the alloy, can be substantially free of nickel, aluminum, titanium, beryllium, or combinations thereof. In one embodiment, the alloy or composite material does not include any nickel, aluminum, titanium, beryllium, or combinations thereof.

For example, this amorphous alloy has the formula (Zr, Ti) _a (Ni, Cu, Fe) _b (Be,
A1, Si, B) _c , where a, b, and c each represent a weight percentage or an atomic percentage. In one embodiment, in atomic percent, a is in the range of 30-75, b is in the range of 5-60, and c is in the range of 0-50. Alternatively, the amorphous alloy can have the formula (Zr, Ti) _a (Ni, Cu) _b (Be) _c , where a
, B, and c each represent a weight percentage or an atomic percentage. In one embodiment, in atomic percent, a is in the range of 40-75, b is in the range of 5-50, and c is in the range of 5-50. The alloy may also have the formula (Zr, Ti) _a (Ni, Cu) _b (Be) _c , where a, b, and c represent weight percentage or atomic percentage, respectively. In one embodiment, in atomic percent, a is in the range of 45-65, b is in the range of 7.5-35,
c is in the range of 10-37.5. Alternatively, the alloy has the formula (Zr) _a (Nb, Ti) _b
(Ni, Cu) _c (A1) may also have _d , where a, b, c, and d each represent a weight percentage or an atomic percentage. In one embodiment, in atomic percent, a is 45-65.
B is in the range of 0 to 10, c is in the range of 20 to 40, and d is in the range of 7.5 to

Fe is _{72 Al 5 Ga 2 P 11 C} 6 B 4. Another example is Fe ₇₂ Al ₇ Zr ₁₀ Mo ₅ W ₂ B ₁₅ . Another iron-based alloy system that can be used for coating herein is disclosed in U.S. Patent Application Publication No. 2010/0084052, the amorphous metal having a composition described in parentheses, for example. In the range of manganese (1-3 atomic%), yttrium (

Atom%), and the balance iron.

The amorphous alloy system described above may further include additional elements, such as additional transition metal elements including Nb, Cr, V, and Co. These additive elements may be present at about 30 wt% or less, such as about 20 wt% or less, such as about 10 wt% or less, such as about 5 wt%. In one embodiment, the optional additive element is at least one of cobalt, manganese, zirconium, tantalum, niobium, tungsten, yttrium, titanium, vanadium, and hafnium, forming carbides and wear resistant. Further improve the properties and corrosion resistance. Further optional elements may include up to about 2% total, preferably less than 1% phosphorus, germanium, and arsenic to reduce the melting point. Other minor impurities should be less than about 2%, preferably less than 0.5%.

In some embodiments, a composition having an amorphous alloy can include a small amount of impurities. By intentionally adding impurity elements, the properties of the composition, such as improved mechanical properties (eg, hardness, strength, fracture mechanism, etc.) and / or improved corrosion resistance can be modified. Alternatively, the impurities may be present as inevitable incidental impurities, such as those obtained as processing and manufacturing by-products. These impurities can be up to about 10 wt%, such as about 5 wt%, such as about 2 wt%, such as about 1 wt%, such as about 0.5 wt%, such as about 0.1 wt%. . In some embodiments, these percentages can be volume percentages instead of weight percentages. In one embodiment, the alloy sample / composition consists essentially of an amorphous alloy (with only a small amount of incidental impurities). In another embodiment, the composition comprises an amorphous alloy (having no observable trace impurities).

In one embodiment, the final part exceeded the critical cast thickness of the bulk solidified amorphous alloy.

In embodiments herein, superplastic forming is possible due to the presence of a supercooled liquid region in which the bulk solidified amorphous alloy can exist as a highly viscous liquid. Large plastic deformation can be obtained. The ability to plastically deform significantly in the supercooled liquid region is the
Or used in the cutting process. In contrast to solids, this liquid bulk solidified alloy deforms locally, which greatly reduces the energy required for cutting and forming. The ease of cutting and forming varies with the temperature of the alloy, mold and cutting tool. As the temperature increases, the viscosity decreases, resulting in easier cutting and molding.

Embodiments herein can utilize a thermoplastic molding process using amorphous alloys, for example, performed at Tg-Tx. As used herein, Tx and Tg are the typical heating rates (eg, 20
Determined from standard DSC measurements in ° C / min).

The amorphous alloy component can have a critical casting thickness, and the final part can have a thickness greater than its critical casting thickness. Furthermore, the time and temperature of the heating and shaping operations are selected such that the elastic strain limit of the amorphous alloy can be substantially maintained at 1.0% or higher, preferably 1.5% or higher. In the context of embodiments herein, the temperature near the glass transition means that the molding temperature can be less than the glass transition, near the glass transition temperature or glass transition temperature, and above the glass transition temperature, it is preferably a temperature lower than the crystallization temperature T _x. The cooling step is performed at a rate similar to the heating rate in the heating step, preferably at a rate exceeding the heating rate in the heating step. The cooling step is also preferably accomplished while the forming and forming loads are still maintained.

The methods, techniques, and apparatus described herein are not intended to limit the described embodiments.

As disclosed herein, an apparatus or system (or device or machine) may be configured to melt and injection mold a material (eg, an amorphous alloy). The apparatus is configured to process such a material or alloy by melting at a high melting temperature and then pouring the molten material into a mold for forming. As will be described further below, the parts of this device are placed in line with each other. According to some embodiments, the parts of the device (or access to the system) are along a horizontal axis.

The following embodiments are for illustrative purposes only and are not intended to be limiting.

FIG. 3 shows a schematic diagram of such an exemplary system. More specifically, FIG. 3 shows an injection molding apparatus or system 10. According to one embodiment, the injection molding system 10 includes a melting zone 12 configured to melt the meltable material received therein, and at least configured to inject the molten material from the melting zone 12 into the mold 16. One plunger rod 1
4. In one embodiment, at least the plunger rod 14 and the melting zone 12
Are provided on a straight line and on a horizontal axis (for example, the X-axis).
Moves substantially through the melting zone 12 in the horizontal direction (eg, along the X axis) to move the molten material into the mold 16. The mold can be placed adjacent to the melting zone.

The material to be melted, or “meltable material”, can be received in this melting zone in any number of shapes. For example, the meltable material may be supplied to the melting zone 12 in the form of an ingot (solid state), semi-solid state, preheated slurry, powder, pellets, and the like. For purposes of illustration only, throughout this disclosure, the meltable material is described and illustrated as being in the form of an ingot 25 that is a solid state raw material. However, the material to be melted is in the form of a solid state, semi-solid state, preheated slurry, powder, pellets, etc., and an injection molding system or apparatus 10.
Note that the form of the material may be received within and is not limited. In some embodiments, a loading port (eg, the illustrated example of the ingot loading port 18) may be provided as part of the injection molding system 10. The loading port 18 may be a separate opening or region provided in the device at any number of locations. In one embodiment, the loading port 18 can be a path through one or more portions of the device. For example, material (eg ingot)
Can be inserted horizontally into the container 20 by the plunger 14 or can be inserted horizontally from the mold side of the injection system 10 (eg, through the mold 16 and / or transported). Through the sleeve 30 and into the container 20). In other embodiments, the meltable material can be fed into the melting zone 12 using other methods and / or other devices (eg, through the opposite side of the injection system).

Melting zone 12 has a melting mechanism configured to receive a meltable material and hold it as it is heated to a molten state. The melting mechanism may be in the form of a container 20, which has, for example, a body configured to receive the meltable material and to melt the material therein. Containers used throughout this disclosure are containers made of materials that have been employed to heat substances to high temperatures. For example, in one embodiment, the container may be a crucible, for example a boat crucible. In one embodiment, vessel 20 is a low temperature hearth melting device configured to be available for meltable material under vacuum (eg, applied by vacuum device 38 or a pump). In some embodiments, the container is a temperature controlled container. The container 20 also has a material (within the receiving or melting portion 24 of the body).
For example, it may have an inlet for charging raw materials. In some embodiments, container 2
The zero body includes a substantially U-shaped structure. However, this illustrated shape is not meant to be limiting. The container 20 can include any number of shapes or configurations. The body of the container may have a length, extend longitudinally and horizontally, whereby molten material is transferred from here horizontally using the plunger 14. The material for heating or melting can be received in the molten portion 24 of the container. The molten portion 24 is configured to receive a meltable material to be melted therein. For example, the molten portion 24 has a surface for receiving material. The container 20 can receive material (eg, in the form of an ingot) within the molten portion 24 using one or more devices (eg, loading ports and plungers) of the injection system for delivery. Further descriptions of container embodiments for use in the system 10 include
This is described below with reference to FIGS.

The body of the container 20 can be configured to receive a plunger rod horizontally through the interior for moving the molten material. That is, in one embodiment, the melting mechanism is on the same axis as the plunger rod, and the body can be configured and / or dimensioned to receive at least a portion of the plunger rod. Therefore, the plunger rod 1
4 is a material melted by moving substantially through the container 20 (after heating / melting)
Can be moved from the container into the mold 16. Referring to the embodiment of the system 10 illustrated in FIG. 3, for example, the plunger rod 14 passes through the container 20 and
It moves horizontally from right to left and moves the molten material into the mold 16 and pushes it out.

In order to heat the melting zone 12 to melt the meltable material received in the container 20,
The injection system 10 also includes a heat source that is used to heat and melt the meltable material. At least the molten portion 24 of the container, if not substantially the entire body itself, is configured to be heated to melt the material received therein. Heating is accomplished, for example, using an induction source 26 disposed in the melting zone 12 that is configured to melt the meltable material. In one embodiment, the induction source 26 is disposed adjacent to the container 20. For example, the induction source 26 may be substantially in the form of a coil disposed in a spiral around its length over the length of the container body (see also FIGS. 4-6). In another embodiment, the induction source 26 is in the form of a coil and is embedded in the body of the container 20 (see description of FIGS. 7-9). Accordingly, the container 20 can be powered using a power supply or power supply to power the induction source / coil 26 to provide a meltable material (eg, an inserted ingot) within the melted portion 24.
Can be configured to melt by electromagnetic induction. Thus, the melting zone 12 can include an induction zone. Induction coil 26 is configured to heat and melt any material contained in container 20 without melting and wetting container 20. The induction coil 26 is radio frequency (RF) towards the melted portion 24 (and towards the container 20 configured as shown in FIGS. 4-6).
Radiate. The container body 20 and the coil 26 may be configured to be disposed in a horizontal longitudinal direction along a horizontal axis (eg, the X axis).

In one embodiment, the container 20 is a temperature controlled container. Such a container may include one or more temperature control tubes, which adjust the temperature of the body of the container 20 during melting of the material received in the container (eg, to force the container to cool). In addition, a fluid (eg, water or other fluid) is configured to flow inside. Such a forced-cooled crucible can also be provided on the same axis as the plunger rod. The cooling tube can help prevent the body of the container 20 itself from overheating and melting. The cooling tube can be connected to a cooling system configured to direct the flow of liquid within the container. The cooling tube may include one or more inlets and outlets for liquid or fluid to flow therethrough. The inlet and outlet of the cooling tube can be configured in any number of ways and is not intended to be limiting. For example, the cooling tube may be positioned relative to the melted portion 24 so that the material therein melts and the container temperature is adjusted (ie, heat is absorbed and the container is cooled). Number of cooling pipes, arrangement and / or
Or the direction should not be limited. The embodiment of FIGS. 4-6 shows an example using a cooling tube 48 in the body of the container. The cooling liquid or cooling fluid may be configured to flow through the cooling tube during melting of the meltable material when the induction source 26 is energized.

After the material is melted in the container 20, the plunger 14 is used to
It can be extruded from the container 20 into the mold 16 for molding into an object, part or component. In the case where the meltable material is an alloy (eg, an amorphous alloy), the mold 16 is configured to form a shaped bulk amorphous alloy object, part or component. Mold 16 has an inlet for receiving molten material therethrough. The outlet of the container 20 and the inlet of the mold 16 can be provided in a straight line and on a horizontal axis, whereby the plunger rod 14 moves horizontally through the body 22 of the container and the molten material is removed from the mold. Type 16
It is injected into the mold through the inlet.

As described above, an injection molding system 1 used for molding a material such as a metal or an alloy.
A system such as 0 can utilize a vacuum when extruding molten material into a mold or die cavity. The injection molding system 10 includes at least a melting zone 12 and a mold 1
6 may further include at least one vacuum source 38 or pump configured to apply a vacuum pressure to 6. This vacuum pressure can be applied to at least a portion of the injection molding system 10 used to melt, move or transfer, and mold the material therein. For example, the container 20 and the transfer sleeve 30
, And the plunger rod 14 may all be under vacuum and / or may be sealed in a vacuum chamber.

In one embodiment, the mold 16 is a vacuum mold that is an encapsulating structure configured to adjust the internal vacuum pressure when molding the material. For example, in one embodiment, the vacuum mold 16 is a first plate ("A" mold or "A") that is positioned adjacent (respectively) to each other.
Second plate (also called “B” mold or “B” plate)
including. Each of the first plate and the second plate typically has a mold cavity associated therewith to mold the molten material therebetween. The mold cavity is configured to mold a molten material received therebetween via an infusion sleeve or transfer sleeve 30. The mold cavity may include a mold cavity for the part to form and mold the part therein.

In general, the first plate can be connected to the transfer sleeve 30. According to one embodiment, the plunger rod 14 is configured to move the molten material from the container 20 through the transfer sleeve 30 to the mold 16. Transfer sleeve 30 (sometimes referred to in the art and herein as a shot sleeve, cold sleeve or infusion sleeve)
May be provided between the melting zone 12 and the mold 16. The transfer sleeve 30 has an opening through which the molten material is received and the mold 16 (using the plunger 14) is received.
Configured to be transported in. The opening may be installed in the horizontal direction along the horizontal axis (for example, the X axis). The transfer sleeve need not be a cold chamber. In one embodiment, at least the plunger rod 14, the container 20 (e.g. its receiving or melting part),
And the opening of the transfer sleeve 30 is provided in a straight line and on a horizontal axis so that the plunger rod 14 moves the molten material into the opening of the transfer sleeve 30 (and
Can be moved horizontally through the container 20 for subsequent passage).

The molten material is pushed horizontally through the transfer sleeve 30 and enters the mold cavity through the inlet (eg, in the first plate), between the first plate and the second plate.
During molding of the material, at least the first plate and the second plate are configured to substantially eliminate exposure of the material therebetween (eg, an amorphous alloy) to at least oxygen and nitrogen. Specifically, a vacuum is applied so that atmospheric air is substantially excluded from the plates as well as their cavities. A vacuum pressure is applied inside the vacuum mold 16 using at least one vacuum source 38 connected to a vacuum line. For example, the vacuum or vacuum level of the system can be maintained at 1 × 10 ⁻¹ to 1 × 10 ⁻⁴ Torr during melting and subsequent molding cycles. In another embodiment, the vacuum level is maintained from 1 × 10 ⁻² to about 1 × 10 ⁻⁴ Torr during the melting and molding process. Of course, other pressure levels or ranges, for ^{example, 1 × 10 -9 Torr~1 × 10} -3 Torr, and / or 1 × 10 ^-3 Torr
~ 0.1 Torr can also be used. A vacuum ejector box (not shown) is configured to remove the molded (amorphous alloy) material (or melted part) from the mold cavity between the first and second plates of the mold 16. This removal mechanism is associated with or connected to an actuating mechanism (not shown) configured to actuate to remove the molded material or part (e.g., after at least the vacuum pressure between the plates is released, After the first and second parts move horizontally away from each other).

The apparatus 10 can employ any number or type of molds. For example, any number of plates can be provided between and / or adjacent to the first and second plates to form the mold. For example, molds known as “A” series, “B” series, and / or “X” series molds may be provided in the injection molding system / apparatus 10.

Thus, the likelihood that the part will be molded and formed uniformly depends on the process performed on the material in the injection molding system 10. Uniformly heating the meltable material and maintaining the temperature of the molten material in such an injection molding apparatus 10 helps to form a uniformly molded part. The configuration of vessel 20 and melting zone 12 can be improved to provide such functionality.

For example, FIG. 4 shows an exemplary schematic of a container 40 that includes a body 42 (or base) for melting meltable material therein. Vessel 40 is a cryogenic hearth melting device configured to be utilized for meltable materials under vacuum (eg, applied by vacuum device 38). The body 42 has a melted portion 44 or region (eg, melted portion 24, etc.) configured to receive meltable material therein that melts (eg, via a loading port as shown in FIG. 8).
The melted portion 44 is configured to receive meltable material to be melted therein. For example, the molten portion 44 has a surface for receiving material. Heating is accomplished using an induction coil 26 disposed adjacent to the body 42 in a spiral pattern that substantially surrounds the length of the body 42 of the container 40. Accordingly, the container 40 is configured to inductively melt material (eg, metal or alloy) in the melted portion 44 by supplying power to the induction coil 26.

As shown in the figure, the main body 42 and the coil 26 surrounding the container 40 are configured to be arranged in the horizontal direction. For example, the container 40 can be configured to be used in an injection molding system that is arranged to melt the material and move the material horizontally (and longitudinally).

In a preferred embodiment, the segment 46 is provided on a different plane than the winding of the induction coil 26, for example, the longitudinal direction of the segment 46 is substantially perpendicular to the direction of coil rotation. In another embodiment, the terminal portion is in the same plane as the coil turns.

In one embodiment, the body 42 of the container 40 includes a substantially U-shaped structure. That is,
Segment 46 is constructed and arranged such that the body has a bottom with a sidewall extending from itself. In one embodiment, each segment may include a substantially rounded and / or smooth surface. For example, the surface of the melted portion 44 can be formed in an arc shape (eg, as shown in FIG. 5) by forming segments with curved top and bottom surfaces. However, the shape and / or surface of the body is not intended to be limiting.

The body 42 of the container 40 is formed from a plurality of elongated segments 46 or terminals that are configured to be electrically isolated from one another. As shown in more detail in FIGS. 5 and 6, the segments 46 are spaced apart from each other so that there is a gap between adjacent segments. Each gap is provided with an insulating material 54. This insulating material is segment 46.
Are electrically isolated from each other so that when the segments are used for melting (when the coil is heated), a current is generated separately for each segment. The net result is that the total power absorbed by the container 40 is reduced. Therefore, the efficiency of the container 40 is improved.

According to one embodiment, a layer of insulating material 54 is applied to one or more surfaces of the container 10 to implement such improvements. In one embodiment, material 54 may be applied in the form of a layer between segments 46. However, it is understood that this material 54 need not be uniform, need not be completely covered, need not be of a particular thickness or dimension, and need not be covered from end to end. Let's be done. Indeed, the amount of insulating material 54 provided between segments 46 may vary. In one embodiment, as shown in detail in FIG. 6, the insulating material 54 can be applied such that a recess 52 is formed on the surface to receive the meltable material. A recess is defined as a space in the structural surface that is configured to reduce contact with the surface. The recesses in the container 40 at least reduce the contact between the meltable material and the surface of the melted portion 44, thereby reducing heat loss and heat transfer. The number and location of the recesses 52 can be predetermined or irregular. For example, the number of recesses may be the number of segments 46, or the number of gaps in which the insulating material 54 is limited (i.e., not all of the gaps between adjacent segments need to have recesses; Some may include a complete layer in between). A recess in the surface of the container extends into and along at least the surface of the melted portion 44. The recesses can be parallel to each other along their entire length. In another embodiment, material 54 may be applied irregularly along the length of each segment 46.

Returning to FIG. 6, each recess 52 extends into the body 42 (e.g., toward the outer surface). The size and dimensions of the recess 52 are not intended to be limiting. In one embodiment,
The recess 52 includes a width and a depth. For example, the width can be the dimension of the opening in the lateral direction (eg, perpendicular to the longitudinal direction of the container 40). In one embodiment, the recess may also include a length (eg, a length relative to the longitudinal direction of the container 40). The dimensions of the recess 52 can vary depending on the size of the gap between adjacent segments. In one embodiment, many recesses of varying depths may be provided on the surface of the molten portion 44 of the container 40. In yet another embodiment, the recess 52 may include multiple depths or dimensions. For example, the recess 52 may include a stepped shape, whereby a portion of the recess may extend a further distance within the body. As another example, the rows (or grooves) of recesses may be provided at various depths along the container surface, depending on the application of insulating material 54 between the segments 46.

In one embodiment, the width or diameter D of the recess 52 is about 0.01 mm to about 1.5 mm. In another embodiment, the width or diameter D of the recess 52 is about 0.01 mm to about 1.0 mm. In one embodiment, the depth or height H of the recess 52 is about 0.01 mm to about 4.0 mm.
It is. In another embodiment, the depth or height H of the recess 52 is from about 0.01 mm to about 2.
0 mm. These dimensions are exemplary and not limiting.

Also, the thickness of the insulating material 54 when applied to one or more regions of the container 40 should not be limiting. In one embodiment, the thickness of the material 54 may vary depending on, for example, the location of the material 54 placement.

Any number and / or types of methods may be used to isolate the insulating material 5 on the segment 46 of the container 40.
4 can be applied and this method should not be limiting. For example, the material 54 is
In some embodiments, it can be applied as a coating. In addition or alternatively, spray coating, laminating, shielding, dipping, thermal spraying, flame spraying, or plasma spraying (thermal, flame, or plasma spraying), plating,
Material 54 can be added to segment 46 using techniques such as chemical vapor deposition, physical vapor deposition processes, and / or other thermal or chemical processes. The process used to apply the material to any surface or region of the container described herein should not be limited to including a consistent and / or uniform coating.

According to another embodiment, the insulating material 54 may be applied as a jacket that encloses the entire segment 46. Thus, each segment 46 may have an insulating coating on its side, top, and bottom.

In one embodiment, the material used to form the body 42 (or segment 46 and / or material 54) is not limited when a material 54 (eg, ceramic) having thermal insulation properties is provided on the surface of the body 42. . For example, the segment 46 of the container 40 can be formed of a material that can be RF sensitive. For example, if the segment 46 is covered with a thermal insulator such as material 54, the sensitivity of the body 42 may be substantially reduced. Also harder,
Coating with material 54 using an alloy with high wear resistance and low conductivity (eg, beryllium copper) can increase power consumption.

Insulating material 54 may be formed of one or more materials or a combination of materials. In the embodiment, the material 54 is a material with poor thermal conductivity, that is, a material with low thermal conductivity. For example, in one embodiment, the material 54 may be a material having a rate of less than one third of the ability to transfer heat compared to the material used to form the body / segment. In one embodiment, material 54 can be a magnetic material. In another embodiment, material 54 can be non-magnetic.

In one embodiment, material 54 may include at least one of the group consisting of ceramic, quartz, stainless steel, titanium, chromium, copper, silver, gold, diamond-like carbon, yttria, yttrium oxide, and zirconia. For example, ceramic is non-conductive to RF energy (ie from induction coil 26), which means that the RF material does not heat the ceramic material and the temperature does not change. By using a low thermal conductivity material, such as material 54, between or on the segments 46 of the container 40, the temperature of the molten material and the container is actively adjusted. In one embodiment, the ceramic can include an oxide, nitride, oxynitride, carbide, or a combination thereof. In another embodiment, the ceramic comprises yttria, silicon nitride, silicon oxynitride, silicon carbide, or a combination thereof. In yet another embodiment, the material 54 can be yttrium oxide.

In an embodiment, the insulating material used for the container may have a low or high thermal conductivity (e.g., FIGS. Embodiments such as those described below in FIG. 13 may use different insulators).

According to one embodiment, the container 40 also provides a fluid (eg, water or other fluid) therein to assist in regulating the temperature of the body 42 while melting the meltable material received in the melted portion 44. There may be one or more temperature control lines 50 in the body 42 that are configured to flow. The cooling pipe 50 serves to prevent the body 40 itself of the container 42 from overheating and melting. The cooling tube 50 may include one or more inlets and outlets for liquid or fluid to flow therethrough. As will be described below, the inlet and outlet of the cooling tube can be configured in any number of ways and is not intended to be limiting. The cooling tube 50 is configured to be disposed within the body 42 relative to the melted portion 44. The cooling tube 50 can be positioned relative to the melted portion 44 so that the surface material melts and the vessel temperature is adjusted (ie, heat is absorbed and the vessel is cooled). For example, for a boat or crucible container that includes a length and extends longitudinally, its molten portion 44 may also extend longitudinally. According to one embodiment, the cooling tube 50 may be disposed longitudinally with respect to the melted portion 44. For example, the cooling tube 50 can be disposed at least at the bottom of the body 42 (eg, in a segment on the lower or bottom surface). In another embodiment, the cooling tubes 50 can be arranged horizontally or laterally.

In another embodiment, each elongate segment 46 may include at least one temperature adjustment line 50 configured to flow liquid through the interior to adjust the temperature of the individual segments during melting. In yet another embodiment, the cooling tube 50 may be configured to cool the segment 46 as a whole. For example, instead of passing the cooling pipe 50 through each terminal portion, a cooling pipe can be provided around the container body 42. In one embodiment where insulating material 54 is provided around the plurality of sides of segment 46, cooling tube 50 may be provided within insulating material 54.

The number, arrangement and / or orientation of the cooling tubes 50 should not be limited. The cooling tube 50 is provided in the bottom surface of the body 42 and / or in any sidewall, and may be provided in any number of positions and orientations. Further, the dimensions (for example, diameter or width) of the cooling pipe are not limited. The dimensions of the cooling tubes can vary, for example, depending on the number of cooling tubes included in the body, or depending on the dimensions of the included segments or materials. This dimension can also be based on the thickness and / or the amount of cooling desired.

The inlet and outlet of the cooling tube of the vessel can be configured in any number of ways. For example, in one embodiment, the cooling fluid can be configured to flow into and out of each cooling tube so that the liquid flows in one direction. In another embodiment, the liquid can be configured to flow in alternating directions, for example, each adjacent line can include alternating inlets and outlets. In addition, the cooling tubes can be configured to have one or more inlets / outlets configured to flow liquid between the cooling tubes. For example, in one embodiment in which the container includes a longitudinally extending cooling tube, the one or more cooling tubes have one or more lateral or extending lines that extend toward another cooling tube. May be included and thereby be in fluid communication with each other. That is, the liquid is configured to flow not only longitudinally along the body, but also between them through a connected cooling tube.

Thus, the above-described embodiments help reduce the amount of energy absorbed by the container, thereby providing more energy to the material to be melted. Since more energy can be supplied, the system can achieve higher melting temperatures. However, it should be noted that this does not necessarily mean that more energy needs to be applied to the induction coil 26. Rather, the container disclosed herein (
For example, when a container 40) is used, a higher melting temperature can be achieved, thereby improving the melting process by allowing a smaller energy application.

In addition, the meltable material, such as an alloy, is brought into a molten state by induction coils (eg, coil
This can be achieved by passing a large amount of current through 6). This creates a local oscillating electromagnetic field. This local electromagnetic field diffuses energy (heat) into the material / alloy due to the resistance of the alloy to eddy current propagation. A side effect of using this technique is that the coil material itself (coil 26) becomes hot due to the resistive heating effect resulting from the current forced through the coil.

In applications where the resistance heating of the coil is significant enough to soften or melt the coil material, some form of coil cooling should be employed. Thus, in addition to or as an alternative to the cooling tube of the vessel, the induction coil disclosed in the embodiments herein can be configured with a cooling system or cooling tube. That is, the same or a separate cooling system can be used to cool the induction coil during heating or system use. For example, FIG. 14 shows a schematic diagram of a cooling system that can be used to cool an induction coil. The “cooling device” can be, for example, a part of the cooling system shown in FIG. This cooling device is a cooling material,
It is configured to supply a liquid, fluid, or gas to one or more parts of the system, which can be an induction coil. Cooling may be “active” where fluid or gas is used to carry heat away from the coil material. According to one embodiment, the gas or fluid is pumped through a coil formed outside the tube, or a surrounding portion of the coil, so that the heat is along the coil towards the point where it is actively cooled. Is spread.

In either case, the cooling fluid or gas is supplied at a temperature that transfers energy (in the form of heat) from the coil material to the cooling fluid or gas, and is carried away downstream or away from the coil to provide a cooling device. This heat energy is removed from the fluid or gas (closed loop system), or the fluid or gas flows out to the atmosphere, ground, holding tank, etc. (open loop system).

A single cooling device can supply cooling water to many different components of the machine,
This component includes, but is not limited to, the induction coil 26 and / or container disclosed herein. The cooling device may have the function of returning the cooling fluid to a fixed temperature and then returning the fluid to the coil so that the temperature of the cooling fluid as it enters the coil is known.

The cooling fluid can be selectively activated to flow or pump into the cooling tube. In some embodiments, the fluid or gas may be pumped or adjacent to the coil only while the coil is activated (ie, heated). In some embodiments, the fluid or gas can be configured to be pumped to maintain the coil sufficiently at a safe operating temperature. For example, the system can be programmed to supply fluid or gas to the cooling tube / system based on sensor readings.

The cooling pipe is a short distance (1 between the cooling device / system and the coil (or vessel) to be cooled
Less than a meter) or over a long distance (a few meters). Thus, the cooling device / system can be located near or adjacent to the injection molding system, within the injection molding system, or at a distance from the injection molding system (eg, in a separate room).

Another embodiment is shown showing a container 60 for holding and melting a meltable material therein, having a body 62 with an inductive coil 66 embedded in the body 62. The induction coil 66 is configured to melt the meltable material received in the melted portion 64. According to one embodiment, the embedded induction coil 66 is configured to surround the melted portion 64. The body 62 has a tubular shape with an opening extending therethrough and forms a melted portion 64. The opening is configured to receive a plunger, such as plunger 14 therethrough, which allows the molten material to move from the body of the melting zone to the mold.

The molten portion 64 has a surface for receiving material. The heating is performed by an induction coil 66 that is helically embedded and configured within a body 62 that substantially surrounds a length of the melted portion 64.
Achieved using. Coil 66 is configured to substantially surround molten portion 64. Accordingly, the system provides power to the induction coil 66 to provide a melting portion 44.
The material (eg, metal or alloy ingot) is configured to melt by induction.
By embedding the coil 66 in the material of the body 62, a streamlined and more efficient melting device is formed, and the coil 66 is arranged so that the material to be melted fills the container with a larger volume fraction. The larger the volume fraction, the more efficient the heating. For example, if the coil is placed about 1 millimeter away from the outer diameter of the amorphous alloy ingot,
The efficiency of the heating process can be increased.

As shown in the figure, the main body 62 and the coil 66 are configured to be arranged in the horizontal direction.
For example, the container 60 can be configured for use in an injection molding system 10 that is arranged to melt the material and move the material in the horizontal (and longitudinal) direction. However, in one embodiment, the container 60 is positioned vertically and can be used in a vertical injection molding system.

The dimensions of the body 62 (e.g., the length, diameter, thickness of the material with the coil embedded therein), the internal melted portion 64 (e.g., diameter) and other portions of the container 60 are determined by the melting zone of the system 10. It can be adjusted according to the 12 dimensions or the dimensions of the part to be melted. The dimensions should not be limiting.

In one embodiment, the body 62 of the container 60 may be formed of a non-conductive dielectric or insulator material (eg, industrial ceramic). By using industrial ceramics, the RF or magnetic field arising from the coil 66 can pass directly through the body 62 and reach the meltable material of the melted portion 64. Thus, by using a ceramic material, the body 62

The loops 70 and 72 are connected to each other via elongated struts 74. The loop and post are made of a conductive material. Each strut has an inherent capacitance that is tuned so that the coil resonates at a particular frequency (eg, causes the RF energy to be dissipated very efficiently at a particular frequency by the coil).

Induction coil 68 is configured to inductively melt material (eg, a metal or alloy ingot) within the melted portion of the associated container by supplying power to induction coil 68. By embedding the coil 68 in the body material, a streamlined and more efficient melting device is formed, and the coil is arranged so that the material to be melted fills the container with a larger volume fraction.
