The single roll method is superior to the twin roll method in terms of continuous productivity, and thus is becoming the mainstream of producing amorphous alloy ribbon.
Since the amorphous alloy material is different from the crystalline alloy, deformation cannot be achieved by dislocation movement because the atomic arrangement inside the amorphous alloy is disordered. The amorphous alloy basically has no macroscopic plastic behavior, which seriously restricts the application of the amorphous material in real life. The narrow and thin amorphous strip in the prior art also limits the application of amorphous materials in building materials.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings of the embodiments of the present disclosure. It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.
In the present application, each term has a meaning generally understood in the art, unless otherwise indicated or a different meaning can be derived from the context.
In the present application, unless otherwise specified, "melting temperature" and "melting point" are used synonymously.
In the present application, unless otherwise specified, "molten steel" and "alloy melt" are used in the same sense.
One aspect of the present application provides a facing material comprising an amorphous alloy foil, which includes: the amorphous alloy film comprises an amorphous alloy foil and an adhesive layer arranged on one side of the amorphous alloy foil, wherein the amorphous alloy foil has a thickness of 15-98 microns and a width of 100mm or more. The amorphous alloy has a long-range disordered structure, shows many excellent mechanical properties different from those of the crystalline alloy, such as high yield strength, high hardness, low Young modulus, higher fracture toughness, good wear resistance, stable chemical properties and excellent corrosion resistance. However, the amorphous alloy has no macroscopic plastic behavior, which severely restricts the application of the amorphous material in real life. The narrow and thin amorphous strip in the prior art also limits the application of amorphous materials in building materials. The inventor of the application finds that the amorphous alloy foil with certain thickness and width is used as a facing material to manufacture the composite material, so that the application field of the amorphous alloy material is widened, the composite material has the excellent characteristics of the amorphous alloy material, can be used as an excellent building material, and has good application prospect. In the present application, the alloy composition and the preparation method of the amorphous alloy foil are not particularly limited as long as the thickness and width thereof are within the desired ranges and have the desired mechanical and chemical properties. Generally, the method for preparing the amorphous alloy foil is a melt rapid quenching method. In the present application, the amorphous alloy foil is required to have a thickness of 15 to 98 μm because too thin amorphous alloy foil is not strong enough and too thick amorphous alloy foil is difficult to prepare. In the present application, the amorphous alloy foil is required to have a width of 100mm or more because too narrow a width is disadvantageous for laying a finishing material on a base structure (substrate) to form a composite material such as a building material, and too narrow a width causes an excessive number of adjacent lines to be processed at the time of laying. The facing material described herein has excellent properties in the following respects: corrosion resistance, flame retardance, high temperature resistance, antibacterial property, electromagnetic shielding, high strength, scraping resistance and low cost. In some embodiments, the facing material includes only the amorphous alloy foil and the adhesive layer disposed on one side of the amorphous alloy foil. The amorphous alloy foil described in the present application has a thickness of 15 to 98 micrometers and a width of 100mm or more, and the amorphous alloy foil refers to a thickness and a width of a single amorphous alloy foil.
In the present application, there is no particular limitation on the material selection of the amorphous alloy foil. In some embodiments, the amorphous alloy foil is an iron-based alloy foil, a nickel-based amorphous foil, a cobalt-based amorphous foil, or an iron-chromium-nickel-based alloy foil. The iron-based alloy foil is an amorphous alloy foil made of raw materials containing more than 60 wt% of iron element. The cost of the iron-based alloy foil is lower. The nickel-based alloy foil is characterized in that the weight content of nickel element in the amorphous alloy foil is higher than that of other elements. The nickel base alloy foil has the best acid corrosion resistance. The cobalt-based alloy foil is an amorphous alloy foil made of raw materials containing more than 50 wt% of cobalt. The cobalt-based alloy foil has excellent soft magnetic characteristics. The Fe-Cr-Ni based alloy foil is an amorphous alloy foil made of raw materials, wherein the content of each Fe-Cr-Ni element is not less than 3 wt%, and the total content of the three elements is not less than 60 wt%. The iron-chromium-nickel base alloy foil has good corrosion resistance and is not easy to be oxidized.
In some embodiments, the amorphous alloy foil of the facing material has a thickness of 30 to 65 microns, or 35 to 50 microns. Within such thickness range the amorphous alloy foil has an HV hardness of more than 800 measured according to GB/T4340.1-1999 and is easy to manufacture. The amorphous alloy foil with the thickness higher than 65 microns needs a larger cooling speed in preparation.
In some embodiments, the amorphous alloy foil of the facing material has a width greater than 200mm, a width greater than 280mm, or a width greater than 350 mm. The amorphous alloy foil prepared by the melt cold quenching method can be placed in a coil. The larger the width of the amorphous alloy foil is, the better the usability of the amorphous alloy foil is for the facing material, so that the amorphous alloy foil is convenient to lay and obtain a proper shape by cutting.
The facing material of the present application is not particularly limited in the selection of the adhesive layer, as long as the amorphous alloy foil can be bonded to the base material. In some embodiments, the adhesive layer is selected from any one of the following: thermosetting adhesives such as epoxy resins, polyurethanes, silicones, and polyimides; thermoplastic binders such as polyacrylates, polymethacrylates, and methanol; phenol-epoxy type adhesives, and the like. The selection of the binder can be made by the person skilled in the art according to the actual need.
In some embodiments, the facing material further comprises a layer of PET disposed between the amorphous alloy foil and the adhesive layer. The PET layer can improve the tearing resistance of the whole facing material and improve the mechanical performance of the facing material. The PET and the amorphous alloy foil can be bonded by adopting an adhesive.
Another aspect of the present application provides a composite material comprising an amorphous alloy foil, comprising the facing material of any one of the preceding claims and a base structure (substrate), wherein the facing material and the base structure are compounded together by an adhesive layer of the facing material. The amorphous alloy foil with certain thickness and width is used as a facing material to manufacture the composite material, the laying is convenient, the composite material has excellent mechanical properties such as high hardness, high fracture toughness and good wear resistance, and the composite material also has good corrosion resistance, the application field of the amorphous alloy material is widened, the composite material has the excellent characteristics of the amorphous alloy material, and the amorphous alloy foil can be used as an excellent building material to obtain good application prospects. In the present application, "the finishing material is combined with the base structure through the adhesive layer of the finishing material" means that the finishing material is attached to at least part of the surface of the base structure, so as to form a composite material, and the attached surface is protected and/or decorated.
The present application is not limited to the base structure, and those skilled in the art can combine the facing material with the base structure according to actual needs. In some embodiments, the material of the base structure is selected from one of the following: non-metal materials such as plastics, wood, composite boards, concrete, etc., and metal materials such as stainless steel, iron, etc. The composite material obtained after compounding takes the substrate structure as a support, has the excellent properties of the amorphous alloy foil, such as high hardness, high fracture toughness and good wear resistance, and also has good high temperature resistance, salt mist resistance, aging resistance, acid and alkali resistance and corrosion resistance on the surface using the facing material.

For example, the presence of a facing material on the outer and/or inner surface of a pipe can significantly improve the corrosion resistance and/or life of the pipe. The facing material is arranged on the concrete base material, so that the corrosion resistance of the material can be improved. For example, the salt spray corrosion resistance of the house can be obviously improved by arranging the facing material on the window or the outer wall of the house facing the sea, so that the service life of the house is completely free from the influence of salt spray corrosion. For example, the facing material may be provided on one or both sides of the panel to provide a composite material having both a pleasing appearance and corrosion and scratch resistance on one side.

In some embodiments, the composite material wherein at least a portion of the surface of the base structure is protected with an aluminum foil facing material comprising an aluminum foil layer, an adhesive layer disposed on one side of the aluminum foil, and a PET layer disposed on the other side of the aluminum foil. The surface protection is carried out by adopting a layer containing an aluminum foil in the prior art, the protection effect is not good than that of the decorative material, and the reason is that the aluminum foil has lower strength and the scratch resistance and the corrosion resistance are far lower than those of the amorphous alloy foil. The mode that the basement structure adopted aluminium foil facing material and this application facing material protection to combine together can save the cost, and facing material mainly protects the region that probably suffers the scraping and corrode the probability higher, and adopts the lacquer painting to protect the region that suffers the scraping and corrode the probability lower.

The iron-based alloy comprises iron, chromium, phosphorus, boron and impurity elements, wherein the iron element accounts for a part by weight, the chromium element accounts for b part by weight, the phosphorus element accounts for c part by weight, the boron element accounts for d part by weight, the impurity element accounts for e part by weight, 66 is larger than or equal to a, 86 is larger than or equal to a, 6 is larger than or equal to b, 21 is larger than or equal to 5, 12 is larger than or equal to c, 0.1 is larger than or equal to d, 1.8 is larger than or equal to 8 and larger than or equal to c +3d, and 13 is larger than or equal to e and smaller than or equal to 1, calculated by total 100 parts by weight. Although the impurity element in the alloy can be nickel, the iron-based alloy does not contain a large amount of expensive nickel element, has low cost and low melting point, and is easy to spray out metal foil. In the present application, an iron-based alloy refers to an alloy having an iron content of more than 60 parts by weight, based on 100 parts by weight of the total alloy weight. The impurity element means an element which does not significantly affect the properties of the iron-based alloy within a specified content range. The metal alloy of the present application has a low melting temperature (below 1150 ℃, for example below 1050 ℃), has suitable melt flowability, and is suitable for preparing corrosion-resistant metal foil with high thickness (more than 35 microns to less than 65 microns) and large width (more than 200mm) by using a single-roll continuous method at low cost. The metal foil can also be used for preparing a composite metal foil with larger thickness and wider width by laminating, has excellent performance and low cost, and can be used in various application fields with high requirements on corrosion resistance and toughness. It should be noted that the alloy of the present application has poor soft magnetic properties, is not a soft magnetic alloy, and is therefore particularly suitable for applications where low requirements for magnetic properties are required.
The range of the elements Fe, Cr, P, B in the alloy can be within the above range, but in some embodiments, 76. ltoreq. a.ltoreq.85, 7. ltoreq. b.ltoreq.11, 7. ltoreq. c.ltoreq.10, and 0.6. ltoreq. d.ltoreq.1.2 in the iron-based alloy. Within these ranges, the iron-based alloy has a lower melting point, enabling more stable production of corrosion resistant metal foils of higher thickness (greater than 35 microns to less than 65 microns) and greater width (greater than 200mm) using a single roll continuous process at lower cost.
In some embodiments, the fe-based alloy has a HV hardness of greater than 800 as measured according to GB/T4340.1-1999, a maximum induction Bm and a remanence Br of less than 70% of the values measured for 1k101 (standard fe-based amorphous soft magnetic alloy strip), such as less than 62% of the values measured for 1k101 (standard fe-based amorphous soft magnetic alloy strip), measured under the same conditions (maximum induction Bm of less than 0.6T measured by scanning, and remanence Br of less than 0.3T), and a 180 ° half-fold toughness of greater than or equal to 2 times, such as greater than or equal to 3 times. The properties of the iron-based alloy are measured by the prepared amorphous alloy foil, so the definition of the properties is also applicable to the amorphous alloy foil prepared by the alloy. The amorphous alloy foil is different from common amorphous soft magnetic alloy, has the maximum magnetic induction intensity Bm and the remanence Br which are obviously lower than those of standard soft magnetic alloy, has good 180-degree folding toughness, and has hardness which is far higher than that of stainless steel (the HV hardness of the stainless steel foil is usually about 500). Without being limited by theory, it is believed that the alloys described herein have poor soft magnetic properties due to the higher content of chromium, and the amorphous alloy foils of the present application, which are prepared by rapid cooling of the alloy melt due to the single roll process described herein, have the excellent toughness and high HV hardness of amorphous alloys without the brittleness of crystalline alloys.
The application also provides an iron-based amorphous alloy foil prepared from the iron-based alloy of any one of the preceding claims, and having a thickness of 10 to 98 microns, or a thickness of 20 to 65 microns, or a thickness of 25 to 50 microns. The iron-based amorphous alloy foil has the advantages of excellent performances of corrosion resistance, flame retardance, high temperature resistance, electromagnetic shielding, high strength, scratch resistance, light weight, low cost and the like. Because the melting point of the alloy of the present application is relatively low, the ejection temperature can be correspondingly low (usually about 1220 ℃ or lower, and even as low as 1100 ℃ or lower), and the cooling capacity required for cooling to a solid is lower than that of an alloy without phosphorus and boron, so that when a foil is prepared by a single-roll method, the cooling efficiency provided by a single roll can rapidly cool a thicker melt to a solid, and a thicker thickness can be prepared. In the case that the foil has a relatively thick thickness, the foil can have relatively high strength, such as hardness, toughness, and the like, so that the foil has a wider application space.
In some embodiments, the iron-based amorphous alloy foil has a width greater than 30mm, a width greater than 60mm, a width greater than 100mm, a width greater than 200mm, a width greater than 280mm, or a width greater than 350 mm. Other methods for preparing amorphous materials, such as a single-roll cooling method, generally cannot prepare amorphous alloy foils with wide widths, so that the application of foils with amorphous properties is greatly limited. The foil of the present application has a wider width and can be used in more application areas. The width described here means a dimension in a direction perpendicular to the machine direction.
In some embodiments, the fe-based amorphous alloy foil has a HV hardness of greater than 800 as measured according to GB/T4340.1-1999, a maximum induction Bm and a remanence Br of less than 70% of the values measured for 1k101 (standard fe-based amorphous soft magnetic alloy strip), such as less than 62% of the values measured for 1k101 (standard fe-based amorphous soft magnetic alloy strip), measured under the same conditions (maximum induction Bm of less than 0.6T and remanence Br of less than 0.3T as measured by scanning), and a 180 ° half-fold toughness of greater than or equal to 2 times, such as greater than or equal to 3 times.
The application also provides an iron-based amorphous alloy foil composite material which comprises at least two layers of metal foils which are mutually stuck in a staggered manner through adhesive layers, wherein at least one layer of metal foil is the iron-based amorphous alloy foil. Through the compounding, the size limitation of the amorphous alloy foil can be completely eliminated, the strength of the foil is further increased, the amorphous alloy foil without size limitation is prepared, and therefore the application field of the amorphous alloy foil can be expanded.
The adhesive layer used in the present application is not particularly limited as long as sufficient adhesion can be secured on the metal foil. In some embodiments the adhesive layer is any one selected from the group consisting of: thermosetting adhesives such as epoxy resins, polyurethanes, silicones, and polyimides; thermoplastic binders such as polyacrylates, polymethacrylates, and methanol; phenol-epoxy type adhesives, and the like. The selection of the binder can be made by the person skilled in the art according to the actual need.
In some embodiments, the composite has a width greater than 350mm, or has a width greater than 500 mm. The composite material of the application can increase the width of the composite material to any suitable size according to the requirement due to the fact that the two layers of metal foils are compounded.
Another aspect of the present invention provides a method for preparing the iron-based amorphous alloy foil described in any one of the preceding claims, comprising the following steps:
step one, smelting and melting ingredients to obtain an alloy melt, wherein the ingredients are calculated by total 100 parts by weight, and the weight parts of the ingredients are respectively as follows: the weight portion of the iron element is a, the weight portion of the chromium element is b, the weight portion of the phosphorus element is c, the weight portion of the boron element is d, the weight portion of the impurity element is e, 66 is more than or equal to a and less than or equal to 86, 6 is more than or equal to b and less than or equal to 21, 5 is more than or equal to c and less than or equal to 12, 0.1 is more than or equal to d and less than or equal to 1.8, 8 is more than or equal to c +3d and less than or equal to 13, and e is less than or equal to 1,
and secondly, enabling the alloy melt to quickly pass through a nozzle gap under pressure, and quickly cooling the alloy melt through the surface of a cooling roller under the traction of a traction roller to obtain the iron-based amorphous alloy foil. In some embodiments, step two is performed at a temperature between 1000 ℃ and 1220 ℃ and at least 50 ℃ above the melting temperature of the alloy melt, for example step two is performed at a temperature between 1100 ℃ and 1220 ℃ and at least 100 ℃ above the melting temperature of the alloy melt.
In some embodiments, the method wherein the nozzle slot has a width of 0.2mm to 0.8mm and a length of 6mm to 500mm, such as 200mm to 350mm, such as 250mm to 320 mm. The width of the cooling roller corresponding to the nozzle slot is more than or equal to the length of the nozzle slot. The width and length of the nozzle slit can be appropriately selected according to the thickness and width of the amorphous alloy foil required, and can be made by those skilled in the art as needed.
In some embodiments, the furnish includes at least one of pure iron, pure chromium, ferrophosphorus, ferroboron.
Another aspect of the present invention provides a method of preparing an iron-nickel chromium-based amorphous alloy foil, comprising:
a melting step: smelting stainless steel, ferrophosphorus and ferroboron together to form an alloy melt, wherein the mass c of phosphorus is 5-12 parts by weight, such as 7-10 parts by weight, the mass d of boron is 0.1-1.8 parts by weight, such as 0.6-1.2 parts by weight, calculated on the total 100 parts by weight, and satisfies 8 ≦ c +3 ≦ d ≦ 13, the impurity content is controlled to be less than 1 part by weight, and the melting temperature of the alloy melt is 1150 ℃ or less, such as 1050 ℃ or less, such as 1000 ℃ or less;
an ejection step: ejecting the alloy melt onto a cooling roller at a temperature of between 1000 ℃ and 1220 ℃ (for example, between 1100 ℃ and 1220 ℃) and at least 50 ℃ higher than the melting temperature of the alloy melt (for example, at least 100 ℃ higher than the melting temperature of the alloy melt), and forming the Fe-Ni-Cr-based amorphous alloy foil.
The inventors of the present application have unexpectedly found that by using a method of adding phosphorus and boron to stainless steel, an alloy can be prepared which has a lower melting point (below 1150 ℃, such as below 1050 ℃, such as below 1000 ℃) and a better fluidity at a lower temperature (between 1000 ℃ and 1220 ℃), which enables the preparation of amorphous alloy foils with higher thickness and wider width by the single roll process described herein. The amorphous alloy foil has excellent properties such as corrosion resistance, flame retardance, high temperature resistance, electromagnetic shielding property, high strength, scratch resistance, low cost, light weight and the like.
In some embodiments, the stainless steel is selected from one or more stainless steels of any of the following grades: 201. 201L, 202, 204, 301, 302, 303se, 304L, 304N1, 304N2, 304LN, 309S, 310S, 316L, 316N, 316J1, 316J1L, 317. In other embodiments, the stainless steel is recycled stainless steel. The choice of stainless steel in the present application is not limited, and any stainless steel of the prior art can be used to prepare the fe-ni-cr-based amorphous alloy foil described herein, and in a preferred embodiment, recycled stainless steel can be used to substantially reduce manufacturing costs.
In some embodiments, the method wherein the alloy melt has a manganese content of less than 2 parts by weight, such as less than 1 part by weight, such as less than 0.2 part by weight. The high manganese content is not beneficial to the forming of the Fe-Ni-Cr-based amorphous alloy foil, so that the sprayed foil is brittle and has no toughness, and the foil cannot be continuously sprayed to prepare the foil.
The mass ratios of various elements in stainless steels of different grades are different, the manganese element content in some stainless steels is higher, and the manganese element content in other stainless steels is lower.
Table 1 shows the mass ratios of the various elements in several different grades of stainless steel.

In some embodiments, the alloy melt has a lower manganese content and does not need to be subjected to additional demanganization, for example, the stainless steel in the batch is 304 stainless steel, and because the manganese content of the 304 stainless steel is lower, the alloy melt has a lower manganese content and can be not subjected to demanganization; in other embodiments, the alloy melt has a higher manganese content and requires additional demanganization, for example, the stainless steel in the batch is 202 stainless steel, and because the manganese content of the 202 stainless steel is higher and the manganese content of the alloy melt is higher, the manganese content can be effectively reduced by selecting a suitable demanganization agent for demanganization. The demanganizing agent is selected by selecting a suitable oxidizing agent. Iron oxide is an economical and relatively effective demanganizing agent, and iron oxides such as FeO and Fe can be used2O3Two forms or a combination thereof.
In some embodiments, the melting step comprises refining the alloy melt at a temperature of 100 ℃ to 200 ℃ above the melting temperature so that the elements in the alloy are well mixed; the impurities refer to other elements which do not obviously influence the properties of the iron-nickel-chromium alloy within the content range. The method of refining the alloy melt is not limited, and those skilled in the art can select the method according to actual conditions. However, the impurities in the alloy melt are not any elements, and the impurity elements refer to other elements which do not significantly affect the properties of the iron-nickel-chromium alloy within the content range, such as elements other than iron-nickel-chromium-phosphorus-boron, such as manganese.
The application also provides an iron-nickel-chromium amorphous alloy foil prepared according to the method of any one of the preceding claims.
The iron-nickel-chromium-based alloy comprises iron element, chromium element, nickel element, phosphorus element, boron element and impurity element, wherein the weight portion of the iron element is a, the weight portion of the chromium element is b, the weight portion of the nickel element is f, the weight portion of the phosphorus element is c, the weight portion of the boron element is d, the weight portion of the impurity element is e, 66 is larger than or equal to a + f is smaller than or equal to 86, 6 is larger than or equal to f is smaller than or equal to 60, 6 is larger than or equal to b is smaller than or equal to 21, 5 is larger than or equal to c is smaller than or equal to 12, 0.1 is larger than or equal to d is smaller than or equal to 1.8, 8 is larger than or equal to c +3d is smaller than or equal to 13, and e is smaller than or equal to 5, wherein the total 100 parts by weight. The iron-nickel-chromium-based alloy can be prepared by smelting stainless steel, ferrophosphorus and ferroboron together, can adopt recycled stainless steel, and has the advantages of low preparation cost, low melting point of the alloy, and easy ejection for preparing metal foil with large thickness and width. The term "iron-nickel-chromium-based alloy" as used herein refers to an alloy having a content of three elements of iron and nickel and chromium of more than 60 parts by weight based on 100 parts by weight of the total alloy.
In some embodiments, the iron-nickel-chromium-based alloy has a composition of 76. ltoreq. a + f. ltoreq.85, 7. ltoreq. b.ltoreq.11, 7. ltoreq. c.ltoreq.10, 0.6. ltoreq. d.ltoreq.1.2, and when Mn is contained in the impurity elements, the Mn content is less than 2 parts by weight, for example less than 1 part by weight, for example less than 0.2 part by weight.
In some embodiments, the iron-nickel-chromium-based alloy has a HV hardness of greater than 800, a maximum magnetic induction Bm and a remanence Br of less than 70% of the values measured for 1k101 (standard iron-based amorphous soft magnetic alloy strip), such as less than 62% of the values measured for 1k101 (standard iron-based amorphous soft magnetic alloy strip), measured under the same conditions (maximum magnetic induction Bm of less than 0.6T, remanence Br of less than 0.3T, measured by scanning), and a 180 ° half-fold toughness of greater than or equal to 2, such as greater than or equal to 3. The properties of the iron-nickel-chromium-based alloy are determined by the prepared amorphous alloy foil, so the definition of the properties is also applicable to the amorphous alloy foil prepared by the alloy. The amorphous alloy foil is different from common amorphous soft magnetic alloy, has the maximum magnetic induction intensity Bm and the remanence Br which are obviously lower than those of standard soft magnetic alloy, has good 180-degree folding toughness, and has hardness which is far higher than that of stainless steel (the HV hardness of the stainless steel foil is usually about 500). Without being limited by theory, it is believed that the alloys described herein have poor soft magnetic properties due to the higher content of chromium, and the amorphous alloy foils of the present application, which are prepared by the single roll method described herein, are made by rapidly cooling the alloy melt, thus having excellent toughness and high HV hardness of amorphous alloys, without brittleness of crystalline alloys, and further improved toughness and prospects for mass production applications due to the addition of nickel relative to the iron-based alloys described herein.
Yet another aspect of the present application provides an iron-nickel-chromium-based amorphous alloy foil prepared from the iron-nickel-chromium-based alloy of any one of the preceding claims, having a thickness of 10 to 98 microns, or a thickness of 20 to 65 microns, or a thickness of 25 to 60 microns. The iron-based amorphous alloy foil has excellent performances of corrosion resistance, flame retardance, high temperature resistance, electromagnetic shielding, high strength, scratch resistance, light weight and the like, and can obtain remarkably reduced cost if recycled stainless steel is adopted as a raw material. Because the melting point of the alloy of the present application is relatively low, the ejection temperature can be correspondingly low (usually about 1220 ℃ or lower, and even as low as 1100 ℃ or lower), and the cooling capacity required for cooling to a solid is lower than that of an alloy without phosphorus and boron, so that when a foil is prepared by a single-roll method, the cooling efficiency provided by a single roll can rapidly cool a thicker melt to a solid, and a thicker thickness can be prepared. In the case that the foil has a relatively thick thickness, the foil can have relatively high strength, such as hardness, toughness, and the like, so that the foil has a wider application space.
In some embodiments, the iron-nickel-chromium-based amorphous alloy foil has a width greater than 30mm, a width greater than 60mm, a width greater than 100mm, a width greater than 200mm, a width greater than 280mm, or a width greater than 350 mm. Other methods for preparing amorphous materials, such as a single-roll cooling method, generally cannot prepare amorphous alloy foils with wide widths, so that the application of foils with amorphous properties is greatly limited. The foil of the present application has a wider width and can be used in more application areas. The width described here means a dimension in a direction perpendicular to the machine direction.
In some embodiments, the iron-nickel-chromium-based amorphous alloy foil has an HV hardness of more than 800 as measured according to GB/T4340.1-1999, a maximum magnetic induction Bm and a remanence Br of less than 70% of the values measured for 1k101 (standard iron-based amorphous soft magnetic alloy strip), e.g. less than 62% of the values measured for 1k101 (standard iron-based amorphous soft magnetic alloy strip), measured under the same conditions (maximum magnetic induction Bm measured by scanning method is less than 0.6T, remanence Br is less than 0.3T), and a 180 ° double fold toughness of 2 or more, e.g. 3 or more.
The application also provides an iron-nickel-chromium-based amorphous alloy foil composite material which comprises at least two layers of metal foils which are mutually stuck in a staggered manner through an adhesive layer, wherein at least one layer of metal foil is the iron-nickel-chromium-based amorphous alloy foil. Through the compounding, the size limitation of the amorphous alloy foil can be completely eliminated, the strength of the amorphous alloy foil is further increased, the amorphous alloy foil without size limitation is prepared, and therefore the application field of the amorphous alloy foil can be expanded.
The adhesive layer used in the present application is not particularly limited as long as sufficient adhesion can be secured on the metal foil. In some embodiments the adhesive layer is any one selected from the group consisting of: thermosetting adhesives such as epoxy resins, polyurethanes, silicones, and polyimides; thermoplastic binders such as polyacrylates, polymethacrylates, and methanol; phenol-epoxy type adhesives, and the like. The selection of the binder can be made by the person skilled in the art according to the actual need.
In some embodiments, the composite has a width greater than 350mm, or has a width greater than 500 mm. The composite material of the application can increase the width of the composite material to any suitable size according to the requirement due to the fact that the two layers of metal foils are compounded.

The method comprises the following steps of mixing industrial pure iron, chromium, phosphorus iron and ferroboron according to the mass percentage shown in the following table, smelting the mixture with the total amount of 10 kilograms in each experiment into an alloy melt in a vacuum furnace, and spraying the alloy melt onto a cooling roller at the temperature of between 1000 and 1220 ℃ and at least 50 ℃ higher than the melting temperature of the alloy melt to form the iron-based amorphous alloy foil.
The preparation method comprises the following steps:
the same single roll apparatus as in fig. 1 (in fig. 1, 1 is an alloy melt, 2 is a nozzle, 3 is a nozzle slit, 4 is a high frequency coil, 5 is a cooling roll, 6 is a stripping gas nozzle, 7 is a pulling roll, and 8 is an amorphous alloy foil) was used to spray an alloy melt composed of the ingredients in the mass percentages shown in the following table from a nozzle made of ceramics mainly composed of silicon nitride onto a Cu-Be alloy cooling roll having an outer diameter of 800mm, to thereby prepare an amorphous alloy foil having a width of 200 mm.

Figure DEST_PATH_GDA0003395354260000201
From the first set of experiments above, it can be seen that the Cr content cannot exceed 26 wt% and that the higher the melting point of the alloy, the less the thick foil is produced and the brittleness of the produced foil is increased.
From the above second and third set of experiments, it can be seen that the mass content of P in the alloy can be between 5% and 12%, and the mass content of B can be between 0.1% and 1.8%, but the condition that the sum of the boron content 3 times and the phosphorus content is between 8% and 13% needs to be satisfied at the same time. When the P content exceeds 12%, the melting point of the alloy is low, the material is not melted, the master alloy turns red, and the foil cannot be produced; when P is less than 5%, the alloy has a high melting point but a high viscosity, and a foil cannot be produced. The mass percent of B in the alloy is less than 2%, when the mass percent of B is more than or equal to 2%, the melting point of the alloy is increased on the contrary, the fluidity is deteriorated, the hole blocking phenomenon is generated, the foil is brittle, and the foil is broken on a traction roller, so that the foil cannot be continuously produced. Phosphorus and boron are used together in this application to adjust the melting point and the fluidity of the alloy, so that there is also a mutual matching ratio between phosphorus and boron, i.e. the sum of the boron content, which is 3 times that of the phosphorus content, and the phosphorus content is between 8% and 13%, beyond which a satisfactory foil cannot be produced.
Example 2 (preparation method of FeNiCrPB foil)
The method comprises the following steps of mixing 304 stainless steel, phosphorus iron and boron iron according to the mass percentages shown in the following table, wherein the total amount of the mixture in each experiment is about 10 kilograms, smelting the mixture into an alloy melt in a vacuum furnace, and spraying the alloy melt onto a cooling roller at the temperature of between 1000 and 1220 ℃ and at least 50 ℃ higher than the melting temperature of the alloy melt to form the iron-based amorphous alloy foil.
The preparation method comprises the following steps:
the same single roll apparatus as in fig. 1 (in fig. 1, 1 is an alloy melt, 2 is a nozzle, 3 is a nozzle slit, 4 is a high frequency coil, 5 is a cooling roll, 6 is a stripping gas nozzle, 7 is a pulling roll, and 8 is an amorphous alloy foil) was used to spray an alloy melt composed of the ingredients in the mass percentages shown in the following table from a nozzle made of ceramics mainly composed of silicon nitride onto a Cu-Be alloy cooling roll having an outer diameter of 800mm, to thereby prepare an amorphous alloy foil having a width of 200 mm. The melting temperature and ejection temperature of the alloy and the preparation results are shown in the following table. The gap of the nozzle was 200mm by 0.7mm, and the gap between the nozzle and the cooling roll was 120 μm. The amorphous alloy foil with the width of 200mm and the thickness of 35 mu m is obtained.
The specific composition employed in this example is as follows.
TABLE 9 the alloy for the fourth set of experiments has the following specific composition
Figure DEST_PATH_GDA0003395354260000211
TABLE 10 preparation of the fourth set of experiments
Figure DEST_PATH_GDA0003395354260000221
From the fourth set of experiments it can be seen that by adding P and B to the stainless steel material, which are similar in content to the first set of experiments, an excellent foil can be formed by the method of the utility model, which foil has a good shiny appearance and has excellent toughness and corrosion resistance. However, when the Mn content is too high, no foil can be formed, and in experiment 4-4, the Mn content is reduced to about 2 parts by weight (based on 100 parts by weight of the molten alloy) by adding a Mn removal step using iron oxide, and thus an amorphous alloy foil of acceptable quality can be ejected. Therefore, the manganese content in the alloy needs to be controlled to be less than or equal to 2 parts by weight, preferably in a lower range. The product prepared by the preparation method of the foil changes waste into valuable, the stainless steel waste is adopted, the inherent chromium and nickel elements in the stainless steel are introduced into the alloy, the chromium is beneficial to improving the corrosion resistance of the alloy, the nickel is an expensive element and can improve the toughness of the alloy, the formed foil not only has high corrosion resistance, but also improves the acid resistance, and meanwhile, the production cost is low, and is even lower than that of the first group to the third group.
It is further noted that phosphorus and boron are the elements that are avoided as much as possible in the preparation process of stainless steel, because the presence of phosphorus and boron can greatly reduce the toughness of stainless steel, and make the steel brittle. However, in the present application, the inventors of the present application have unexpectedly found that the addition of phosphorus and boron elements to stainless steel alloys can greatly reduce the melting temperature of the steel, so that the alloys can be used to continuously produce amorphous alloy foils having a relatively large thickness and a relatively wide width by a single-roll method. Without being bound by theory, it is believed that the amorphous alloy foil produced in the present application has an amorphous composition, undergoes rapid cooling during the preparation process, does not form crystals, and thus has good hardness and toughness, is isotropic, and has excellent properties that crystalline alloys such as stainless steel do not have.
Comparative example 1 (comparative example, preparation of ordinary Fe-based amorphous alloy foil)
In a similar manner to that of example 1, except that a general iron-based amorphous material was used to prepare the amorphous alloy foil, the alloy was composed of, by mass, 80 parts by weight of Fe, 16 parts by weight of Si, and 4 parts by weight of B. It was found that foils with a thickness above 30 microns and a width exceeding 200mm could not be formed.
Performance testing
The foils obtained in the above examples were tested for the following properties.
The test methods for various properties are as follows:
HV hardness was measured using a Shenzhen Senyu instrument Vickers hardness tester from Senyu instruments and Equipment Limited.
Bm (T), Br (T) and Hc (A/m) were measured using an industrial magnetic test apparatus of Oerson technologies, Inc. of Hunan province.
The toughness of the material (called 180-degree folding toughness or 180-degree folding non-breaking times) is measured by folding the foil 180 degrees, and the specific test method comprises the following steps of folding and flattening the foil 180 degrees (for the first time), then reversely folding and flattening the foil 180 degrees (for the second time) along the same folding line, repeating the steps until the foil is broken, and recording the folding times.
The results of the tests are shown in table 11.
