preparation example Construction

[0021] The preparation method of the above-mentioned zirconium-based amorphous alloy specifically includes the following steps:

[0022] S1: Ingredients. Each composition is compounded according to a certain atomic percentage within the range of the above composition formula, for example, according to each composition and atomic percentage in Table 1. In the batching process, metal rods, blocks, ingots, plates and other materials with a purity greater than 99.9% of Zr, Cu, Al, Ni, Ti, Er, etc. can be alloyed according to the composition and atomic percentage in Table 1.

[0023] S2: Smelting. The prepared raw materials are put into the vacuum induction melting furnace. After vacuuming, the alloy raw materials are melted to completely melt, and stirred to make the ingredients evenly blended.

[0024] S3: cooling to form an amorphous alloy. The molten alloy material is cast into a metal mold for cooling treatment, so as to obtain a zirconium-based amorphous alloy ingot with t...

The invention also provides a method for preparing the zirconium-based amorphous alloy.

Description

technical field [0001] The invention relates to the field of metal alloys, in particular to a zirconium-based bulk amorphous alloy and a preparation method thereof. Background technique [0002] Bulk amorphous alloys have been widely used in electronics, machinery, and chemical industries due to their high strength, toughness, wear resistance, corrosion resistance, excellent soft magnetic properties, and superconducting properties. Zirconium-based bulk amorphous alloy is one of the most widely used bulk amorphous alloys. Due to the high strength of zirconium-based bulk amorphous alloy materials, relevant key components made of zirconium-based bulk amorphous alloy materials have been used in products such as golf clubs and aerospace solar wind collectors. [0003] Amorphous alloys are produced by rapidly cooling alloy melts below the glass transition temperature (Tg) at a certain cooling rate. The slower the cooling rate required for a material to form an amorphous structur...
