preparation example Construction

[0042] Another aspect of the present application also provides a method for preparing a zirconium-based amorphous alloy, including: melting and cooling the raw material of the amorphous alloy to obtain a zirconium-based amorphous alloy;

[0043] Wherein, the raw material of the amorphous alloy is compounded according to the mass converted from the composition of the above-mentioned zirconium-based bulk amorphous alloy.

[0044] As an example, the smelting, cooling and forming process can include:

[0045] S1 melting the raw materials of amorphous alloys except zirconium to obtain alloy ingots;

[0046] S2 mixes the zirconium element with the alloy ingot, and performs smelting treatment to obtain the master alloy ingot;

[0047] In S3, the master alloy ingot is subjected to suction casting to obtain a zirconium-based amorphous alloy.

[0048] The inventor found during the preparation process that the raw materials of the amorphous alloy have different melting points, and the ...

Description

technical field [0001] The present application relates to the field of amorphous alloys, in particular to a nickel-free and beryllium-free zirconium-based amorphous alloy and its preparation method and application. Background technique [0002] Amorphous alloys, also known as liquid metals or metallic glasses, are a new class of high-performance metallic materials discovered in the 1960s. Amorphous alloys are generally formed by the rapid solidification of molten alloy melts so that the system has no time to crystallize. Since the atomic arrangement of amorphous alloys inherits the long-range disordered structure of the liquid state, it has many excellent mechanical, physical and chemical properties. It has broad application prospects in structural materials, micro precision devices, sports equipment, consumer electronics, etc. [0003] The reported zirconium-based amorphous alloys have many components whose critical glass-forming ability can reach more than 10mm. However, ...
