Problems solved by technology

In the conventional amorphous alloy preparation process, due to the limited range of reduction, the harsh production process greatly increases the production cost of amorphous alloy products, making this type of zirconium-based amorphous alloy still remain in the laboratory and cannot be mass-produced. Thus limiting the wide application of amorphous alloys

preparation example Construction

[0033] The preparation method of the zirconium-based amorphous alloy of the present invention can adjust the crystalline phase in the zirconium-based amorphous alloy by controlling the composition of the zirconium-based amorphous alloy and controlling the cooling and forming conditions according to conventional methods in the art and different proportions of the amorphous phase. The cooling forming conditions include cooling speed, pressure, mold material, mold thermal conductivity and the like. Among them, the cooling rate is one of the key factors controlling the ratio of crystalline phase and amorphous phase in zirconium-based amorphous alloys, and the selection range of conditions such as pressure, mold material, and mold thermal conductivity is wide, and the matching selector must ensure The cooling and forming conditions described above can be met only if an appropriate cooling rate can be obtained. In known casting methods, the volume fraction of the crystalline phase ...

Abstract

The invention belongs to the technical fields of metal materials and metallurgy, relates to an amorphous alloy material, and particularly relates to a zirconium-based amorphous alloy and a preparation method thereof. By adjusting the atomic percentage content of each component in the zirconium-based amorphous alloy and adding nonmetallic elements Y and Sc into the zirconium-based amorphous alloy, the preparation requirement on the amorphous alloy can be lowered; more importantly, on the premise of not reducing the comprehensiveness, the high requirement on the purity of raw material is greatly lowered while a certain quantity of impurity elements can be allowed to be reserved in the raw material. Therefore, by properly adjusting the proportion of the nonmetallic elements such as Si and C in the amorphous alloy, the comprehensive performance of the zirconium-based amorphous alloy is not influenced, and the stress on the raw material cost can be reduced in industrial batch production. Through the preparation method provided by the invention, a large zirconium-based amorphous alloy with critical dimension of over 3mm can be obtained; the zirconium-based amorphous alloy has excellent mechanical property, and the requirement on the purity of raw materials and the content of impurity elements is low.
