Title:
REFRACTORY HIGH-ENTROPY AMORPHOUS ALLOY MATERIAL, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/078011
Kind Code:
A1
Abstract:
Disclosed is a refractory high-entropy amorphous alloy material, comprising three or more refractory metal elements among Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W and Re, and one or two non-refractory metal elements among Al, Si, Co, B and Ni, the refractory high-entropy amorphous alloy material having an amorphous structure. The refractory high-entropy amorphous alloy material has high corrosion resistance and mechanical performance. Further disclosed is a preparation method for said refractory high-entropy amorphous alloy material, which comprises: performing batching according to the atomic fractions of the respective elements of a refractory high-entropy amorphous alloy material, and uniformly smelting to obtain a master alloy ingot; and after melting the mother alloy ingot, spraying same onto the surface of a rotating copper roller to obtain a refractory high-entropy amorphous alloy strip. The method is simple and efficient, and may be used in large-scale industrial production. Also disclosed is a use of the refractory high-entropy amorphous alloy material in pipe transportation in nuclear reactors and nuclear power and corrosion environments.
