METAL-MATRIX COMPOSITE BASED ON HIGH-ENTROPY ALLOY Russian patent published in 2023 - IPC C22C30/00 C22C1/10 C22C32/00 

FIELD: metallurgy.

SUBSTANCE: metal-matrix composites based on a high-entropy alloy. Invention can be used for structural applications in aircraft and power engineering, including at high temperatures. Metal-matrix composite Al₅Nb₂₄Ti₄₀V₅Zr₂₆/TiB₂ obtained by vacuum-arc remelting in pure argon of aluminium, niobium, titanium, vanadium, zirconium with the addition of TiB₂ with an average particle size of 4 mcm, contains a matrix of high-entropy alloy Al₅Nb₂₄Ti₄₀V₅Zr₂₆ and a reinforcing component TiB₂, while the matrix alloy contains: 5 at.% of aluminium, 24 at.% of niobium, 40 at.% of titanium, 5 at.% of vanadium and 26 at.% of zirconium, and the metal matrix composite contains 1% by weight of TiB₂.

EFFECT: invention is aimed at obtaining a metal-matrix composite with high tensile strength, yield strength and tensile plasticity at room temperature.
