Abstract

The invention relates to a method for preparing zirconium-base amorphous alloy with plasticity at room temperature, and relates to a method for preparing amorphous alloy, which solves the problem of poor plasticity at room temperature of the amorphous alloy in the prior art. The method comprises the following steps of: filling a zirconium-base amorphous alloy raw material into a water-cooling copper crucible of an arc furnace, vacuumizing a smelting chamber, introducing hydrogen and argon into the smelting chamber according to a certain ratio, smelting the raw material of the zirconium-base amorphous alloy in a mixed atmosphere, and preparing by a copper mold suction casting method to obtain the zirconium-base amorphous alloy with the plasticity at room temperature. The zirconium-base amorphous alloy has excellent plasticity at room temperature, and the plasticity is improved by 7 times. The method can be widely applied to the plastification of massive amorphous alloy, so that the amorphous alloy can be applied in fields of aerospace, weapon industry, precision machines, information technology and the like.

Description

technical field [0001] The invention relates to a method for preparing an amorphous alloy. Background technique [0002] The structure of amorphous alloy is a new type of alloy material with short-range order and long-range disorder, which is similar to liquid structure. Due to their special microstructure, they have excellent mechanical, physical and chemical properties. These characteristics make amorphous alloys have application prospects in aerospace, weapon industry, precision machinery and information technology. At the same time, amorphous itself also has weaknesses, which limit its application. The main difficulty in the application of amorphous alloys is: the plasticity at room temperature is poor, generally between 1% and 2%, and it is difficult to be used as an industrial material. Contents of the invention [0003] The invention aims to solve the problem of poor room-temperature plasticity of the amorphous alloy prepared in the prior art, and provides a meth...
