Abstract

The invention relates to an amorphous alloy preparation technology, in particular to a method for preparing a copper-based amorphous alloy from standard coarse copper. The raw materials are prepared according to a certain proportion by using the standard coarse copper and pure aluminum, the alloy ingot is prepared by melting in a vacuum arc furnace, and the alloy ingot is obtained by grinding andremoving impurity elements adsorbed on the surface of the alloy ingot. A copper-titanium-zirconium amorphous alloy component is prepared by using the alloy ingot, and a copper-based amorphous alloy rod is prepared by melting in a vacuum arc furnace and by a suction casting method, or a copper-based amorphous alloy strip is prepared by spin-quenching of a vacuum copper roller. According to the method, the copper-based amorphous alloy can be prepared by using the crude copper as a raw material, and a good technical means is provided for preparing the copper-based amorphous alloy from the industrial low-purity raw material.

Description

technical field [0001] The invention relates to an amorphous alloy preparation technology, in particular to a method capable of preparing a copper-based amorphous alloy by using standard crude copper (the mass fraction of copper is 98.5%) raw materials. Background technique [0002] Amorphous alloys are structurally disordered amorphous metallic materials. In the preparation technology, a higher cooling rate is required to realize the "freezing" of the liquid structure of the corresponding alloy. But, since amorphous alloy produces, except its preparation process must be in high vacuum equipment (vacuum degree reaches 10 -3 Pa above), inert gas protection, also used higher purity raw materials (purity not less than 99.9at.%). The use of high-purity raw materials has caused a sharp increase in the production cost of amorphous alloys, which is obviously not conducive to the promotion and use of amorphous alloys. [0003] Compared with high-purity metal raw materials, indust...
