Abstract

The invention relates to the technical field of alloy ingots, and in particular relates to a zirconium-based alloy ingot and a preparation method thereof as well as a prepared zirconium-based amorphous alloy. The preparation method of the zirconium-based alloy ingot comprises two steps, namely, a vacuum arc melting method and a vacuum high frequency melting method, wherein the vacuum arc melting method comprises steps of mixing and melting Ni metal and a high melting point method Nb metal, thereby reducing the melting temperature; in addition, except the impurities in the raw materials in the vacuum arc melting method, no other impurities are mixed, so that the purity of the alloy is ensured; a mother alloy obtained by using the vacuum arc melting method is further mixed with the rest materials for secondary melting, thereby obtaining a five-element alloy ingot with accurate proportion. The zirconium-based alloy ingot is die-cast in a vacuum environment, a cooling speed expected by over-cooling is met so as to prevent the materials from crystallization, and the zirconium-based amorphous alloy with the thickness of 0.5-3mm can be manufactured.

Description

technical field [0001] The invention relates to the technical field of alloy ingots, in particular to a zirconium-based alloy ingot, a preparation method thereof, and a prepared 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 material. [0003] The zirco...
