MULTICOMPONENT WIRE FOR PRODUCTION OF AlCoCrFeNi HIGH-ENTROPY ALLOY Russian patent published in 2021 - IPC B23K35/30 B23K35/08 B21F15/04 B21C23/22 

FIELD: multicomponent wire production.

SUBSTANCE: invention relates to the creation of a multicomponent wire intended for wire-arc additive manufacturing, and can be used for production by layer-by-layer cladding of AlCoCrFeNi high-entropic alloy composition. The multicomponent wire contains an aluminum conductor of a circular cross-section and two conductors of a circular cross-section with a diameter of not more than 0.4 mm, one of which is a chromium-nickel wire Х20Н80, and the other is a wire made of precision alloy 29NK. All cores are twisted in a spiral to obtain the diameter of the multicomponent wire no more than 1 mm, while the aluminum content in the aluminum wire is 99.95%, and its diameter is no more than 0.5 mm.

EFFECT: wire provides a high-entropy alloy with high mechanical properties.
