HIGH-ENTROPY ALLOY AND METHOD OF ITS DEFORMATION-HEAT TREATMENT Russian patent published in 2023 - IPC C22C30/00 C22F1/16 C22C38/30 C21D8/00

Abstract RU 2790708 C1

FIELD: metallurgy; high entropy alloys.

SUBSTANCE: high entropy alloy contains components in the following ratio: Fe₃₈Mn₄₀Co₁₀Cr₁₀N₂. The method for obtaining a high-entropy alloy includes melting the alloy, Fe₃₈Mn₄₀Co₁₀Cr₁₀N₂ cold rolling and subsequent annealing by vacuum-arc remelting. Cold rolling is carried out up to the degree of deformation of 80%, and subsequent annealing is carried out at a temperature of 700-900°C for 10 min with air cooling.

EFFECT: alloy has high values of strength and ductility after deformation-heat treatment: tensile strength is 943-1103 MPa, yield strength is 644-900 MPa and tensile ductility at room temperature is 35-51%.
