Title:
HIGH-ENTROPY ALLOY-BASED NANO SUPER-HARD COMPOSITE MATERIAL REINFORCED BY EMBEDDED PARTICLES, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/231744
Kind Code:
A1
Abstract:
The present application relates to the technical field of metal-based composite materials. Disclosed are a high-entropy alloy-based nano super-hard composite material reinforced by embedded particles, and a preparation method therefor. Reinforcing-phase particles and a high-entropy alloy matrix in the composite material have good wettability and have good interface bonding, such that the wear resistance of the composite material can be improved, and the shedding of reinforcing-phase particles during friction can be effectively avoided. The composite material comprises a high-entropy alloy matrix and reinforcing-phase particles, wherein the reinforcing-phase particles are dispersed in the high-entropy alloy matrix; the high-entropy alloy matrix comprises a basic matrix and a reinforcing matrix, the basic matrix comprising Al, Co, Cr, Fe, Ni and Mn, and the reinforcing matrix comprising Mo, Nb and Zr; and the reinforcing-phase particles comprise WC and TiC.
