Abstract

The invention relates to the technical field of alloy ingots, and particularly relates to a low-price Zr-based alloy ingot and a preparation method thereof and a prepared low-price Zr-based amorphous alloy. According to the invention, high-purity Zr is replaced with Zr-2 and Zr-4, and then a low-price Zr-based alloy ingot is prepared by using a vacuum arc melting method and a vacuum high-frequency melting method. Because high-purity Zr is replaced with Zr-2 and Zr-4, the price of the Zr-based alloy ingot is greatly reduced. Meanwhile, Zr2 and Zr4 contain 1.4% of Sn in percentage by weight, so that the replaceable Nb maximum range can reach 50% of the Nb content of the low-price Zr-based alloy ingot. The low-price Zr-based alloy ingot is subjected to pressure casting in a vacuum environment for satisfying the cooling speed required for super-cooling so as to restrain the crystallization of materials, therefore, a low-price Zr-based amorphous alloy with a thickness of 0.5-3 mm can be manufactured.

Description

technical field [0001] The invention relates to the technical field of alloy ingots, in particular to a low-priced zirconium-based alloy ingot, a preparation method thereof, and a prepared low-priced zirconium-based amorphous alloy. Background technique [0002] Amorphous alloys are similar to liquids and are alloys with irregular atomic structures, so they are also called amorphous alloys or Amorphous alloys. Under normal circumstances, the atoms of metals are arranged in an orderly manner to form a crystalline structure, but the atoms of amorphous alloys are arranged irregularly and have no crystalline structure, so they have higher strength, better elasticity, and lighter weight than ordinary metal materials. So when it was first developed, it caused a sensation in the metal industry. Amorphous alloys can be freely molded like plastics after being heated properly, so the development of this method of manufacturing amorphous alloys is leaping into a new industrial materia...
