- glassy alloys consisting essentially of about 60 to 90 atom percent of at least one element of iron, nickel, cobalt, vanadium and chromium, about 10 to 30 atom percent of at least one element of phosphorus, boron and carbon and about 0.1 to 15 atom percent of at least one element of aluminum, silicon, tin, germanium, indium, antimony and beryllium. Up to about one-fourth of the metal may be replaced by elements which commonly alloy with iron and nickel, such as molybdenum, titanium, manganese, tungsten, zirconium, hafnium and copper. Chen et al.
- wires of glassy alloys having the general formula T ; X ; , where T is a transition metal and X is an element selected from the group consisting of phosphorus, boron, carbon, aluminum, silicon, tin, germanium, indium, beryllium and antimony, and where "i” ranges from about 70 to 87 atom percent and "j” ranges from about 13 to 30 atom percent.
- iron-chromium glassy alloys consisting essentially of about 1 to 40 atom percent chromium, 7 to 35 atom percent of at least one of carbon, boron and phosphorus and the balance iron. Up to about 40 atom percent of at least one of nickel and cobalt, up to 20 atom percent of at least one of molybdenum, zirconium, titanium and manganese and up to about 10 atom percent of at least one of vanadium, niobium, tungsten, tantalum and copper may also be employed.
- Elements useful for improving mechanical properties include molybdenum, zirconium, titanium, vanadium, niobium, tantalum, tungsten, copper and manganese, while elements effective for improving the heat resistance include molybdenum, zirconium, titanium, vanadium, niobium, tantalum and tungsten.
- French specification 2,281,434 relates to amorphus i.e. glassy alloys containing mixtures of metalloids and metals including alloys containing both phosphorus and boron.
- French specification 2,317,370 also discloses alloys containing molybdenum or tungsten and at least 15% of metalloid in a glassy alloy.
- substantially totally glassy alloys containing a low boron content as a first component, plus molybdenum or tungsten as a second component in conjunction with one of the metals cobalt, iron and nickel are provided.
- the glassy alloys of the invention consist essentially of about 5 to 12 atom percent boron, one only of the members selected from the group of 20 to 6Q percent molybdenum and 13 to 40 atom percent tungsten and the balance essentially one of the group iron, cobalt and nickel.
- glassy alloys containing all three of the metals cobalt, iron and nickel with the above specified boron and second component molybdenum, tungsten and mixtures thereof are provided wherein each of the metals cobalt, iron and nickel is present in an amount of at least about 5 atom percent, plus incidental impurities.
- the alloys of the invention evidence hardness values of at least about 1000 Kg/mm 3 , ultimate tensile strengths of at least about 2275 MPa (330 Kpsi) and crystallization temperatures of at least about 445°C.
- the glassy alloys of the invention consist essentially of (I) about 5 to 12 atom percent boron together with (II) one only of the group consisting of molybdenum (about 20 to 60 wt%) and tungsten (about 13 to 40 wt%) with the balance being one of the group iron, cobalt and nickel or (III) glassy alloys containing at least 5 atom percent of all three metals, cobalt, iron and nickel in amounts of at least 5 atom percent wherein the amount of molybdenum, tungsten or mixtures thereof, is used in lesser quantities of about 5 to 15 atom percent together with boron in specified amounts of 5 to 12 atom percent.
- the boron is present in amounts of 8 to 10 atom percent and the molybdenum and tungsten as component II in amounts of 30 to 50 atom percent and as component III in amounts of 8 to 12 atom percent.
- glassy alloys of the invention include
- the glassy metal alloys of the invention comprise three components: the first component is boron in amounts of from about 5 to about 12 atom percent; the second component is a refractory metal of the group molybdenum in amounts of 20 to 60 atom percent and tungsten in amounts of from about 13 to 40 atom percent; and the third component comprising the balance of the alloy is selected from the group cobalt, iron and nickel.
- the low boron content, the refractory metal content and the third component are interdependent.
- rapidly quenched ribbons are not totally glassy. Rather, the rapidly quenched ribbons contain crystalline phases, which may comprise a substantial fraction of the material, depending on specific composition.
- the rapidly quenched ribbons containing crystalline phases or mixtures of both glassy and crystalline phases have inferior mechanical properties, i.e., low tensile strength, and are brittle.
- such ribbons having thicknesses up to 38 11m (0.0015 inch), will fracture if bent to a radius of curvature less than 100 times the thickness.
- compositions containing such low metalloid content do not form glassy alloys at the usual quench rates.
- compositions containing such low metalloid content form brittle glassy alloys. If the alloys do not contain these metals in the respective proportions then, in general, the alloys do not form fully glassy ductile ribbons.
- rapidly quenched ribbons are substantially totally glassy and possess superior mechanical properties, i.e., high tensile strength and ductility.
- glassy ribbons of the invention can be bent without fracture to a radius of curvature about 10 times the thickness.
- alloying elements include the transition metal elements (Groups IB to VIIB and VIII, Rows 4, 5 and 6 of the Periodic Table, other than the elements mentioned above) and metalloid elements (carbon, silicon, aluminum, and phosphorus), the amounts, as already made clear must not be such as to interfere with the essential components of the alloy.
- Thermal stability is an important property in certain applications. Thermal stability is characterized by the time-temperature behavior of an alloy, and may be determined in part by differential thermal analysis (DTA). Glassy alloys with similar crystallization behavior as observed by DTA may exhibit different embrittlement behavior upon exposure to the same heat treatment cycle.
- DTA measurement crystallization temperatures T e can be accurately determined by heating a glassy alloy (at about 20° to 50°C/min) and noting whether excess heat is evolved over a limited temperature range (crystallization temperature) or whether excess heat is absorbed over a particular temperature range (glass transition temperature). In general, the glass transition temperature is near the lowest, or first, crystallization temperature T el and, as is conventional, is the temperature at which the viscosity ranges from about 10 12 to 10 13 Pas (10 13 to 10 14 poise).
- the glassy alloys of the invention are formed by quenching an alloy melt of the appropriate composition at a rate of at least about 10 5 °C/sec.
- An alloy melt of the appropriate composition at a rate of at least about 10 5 °C/sec.
- a variety of techniques are available, as is well-known in the art, for fabricating rapidly-quenched continuous filament.
- a particular composition is selected, powders of the requisite elements (or of materials that decompose to form the elements) in the desired proportions are melted and homogenized, and the molten alloy is rapidly quenched on a chill surface, such as a rapidly rotating cylinder.
- the alloys of the invention are substantially totally glassy, as determined by X-ray diffraction.
- glass as used herein, means a state of matter in which the component atoms are arranged in a disorderly array; that is, there is no long range order.
- Such a glassy alloy material gives rise to broad, diffuse diffraction peaks when subjected to electromagnetic radiation in the X-ray region (about 0.01 to 50 A wavelength). This is in contrast to crystalline material, in which the component atoms are arranged in an orderly array, giving rise to sharp diffractions peaks.
- substantially totally glassy means a state of matter having crystalline and amorphous phases, the amorphous phase constituting at least about 80 percent of the combined phases. Thermal stability of the alloys improves as the degree of amorphousness thereof approaches 100%. Accordingly, totally glassy alloys, possessing a single, amorphous phase constituting 100% of the component atoms are preferred.
- the glassy alloys of the invention evidence hardness values of at least about 1000 kg/mm 2 , ultimate tensile strengths of at least about 2413 MPa(350 Kpsi) and crystallization temperatures of at least about 445°C.
- Preferred alloy compositions consist essentially of about 50 to 65 atom percent of one of the iron group metals of iron, cobalt and nickel, about 13 to 35 atom percent of the remaining two iron group metals, about 8 to 12 atom percent of at least one of molybdenum and tungsten and about 8 to 10 atom percent boron.
- the alloys having such preferred compositions are especially capable of being fabricated as good quality, ductile ribbons exhibiting high tensile strength.
- the high mechanical strength and high thermal stability of the glassy alloys of the invention render them suitable for use as reinforcement in composites for high temperature applications.
- Alloys were prepared from constituent elements of high purity (99.9%). The elements with a total weight of 30 g were melted by induction heater in a quartz crucible under vacuum of 133 mPa (10- 3 Torr). The molten alloy was held at 150° to 200°C above the liquidus temperature for 10 min and allowed to become completely homogenized before it was slowly cooled to the solid state at room temperature. The alloy was fractured and examined for complete homogenity.
- the chill substrate used in the present work was beryllium-copper alloy in a heat-treated condition having moderately high strength and thermal conductivity.
- the substrate material contained 0.4 to 0.7 wt% beryllium, 2.4 to 2.7 wt% cobalt and copper as balance.
- the substrate was kept rotating at a surface speed of 20.3 m/s (4000 ft/min).
- the substrate and the crucible were contained inside a vacuum chamber evacuated to 133 mPa (10- 3 Torr).
- the melt was spun as a molten jet by applying argon pressure of 34.5 kPa (5 psi) over the melt.
- the molten jet impinged vertically onto the internal surface of the rotating substrate.
- the chill-cast ribbon was maintained in good contact with the substrate by the centrifugal force acting on the ribbon against the surface.
- the ribbon was ejected off the substrate by nitrogen gas at 207 kPa (30 psi), two- thirds circumferential length away from the point of jet impingement.
- the vacuum chamber was maintained under a dynamic vacuum of 2.7 kPa (20 Torr).
- the substrate surface was polished with 320 grit emery paper and cleaned and dried with acetone prior to the start of the casting operation.
- the as-cast ribbons were found to have good edges and surfaces.
- the ribbons had the following dimensions: 25.4 to 30.5,um (0.0001 to 0.0012 inch) thickness and 381 pm to 508!1m (0.015 to 0.020 inch) width
- the degree of glassiness was determined by X-ray diffraction. A cooling rate of at least about 10 5 °C/sec was attained by the quenching process.
- Hardness was measured by the diamond pyramid tehcnique using a Vickers-type indenter, consisting of a diamond in the form of a square-base pyramid with an included angle of 136° between opposite faces. Loads of 100 g were applied. Crystallization temperature was measured by differential thermal analysis at a scan rate of about 20°C/min. Ultimate tensile strength was measured on an Instron machine using ribbons with unpolished edges. The gauge length of the specimens was 25.4 mm (1 inch) and the cross-head speed was 8.46,ums/s (0.02 in/min).
- Table V sets forth compositions outside the scope of the invention and the results of structural analysis by X-ray diffraction in chill cast ribbons of these compositions prepared as above, and the brittleness of the ribbons.
