METHOD FOR THERMOMECHANICAL PROCESSING OF PROMISING COPPER ALLOYS Russian patent published in 2022 - IPC C22F1/08 

FIELD: non-ferrous metallurgy.

SUBSTANCE: invention relates to the thermomechanical processing of copper alloys intended for electrical products, in particular for contact wires of a high-speed rail network, high-strength copper wires and cables for the needs of the automotive and aviation industries. The method for thermomechanical processing of copper low alloys includes rolling, equal-channel angular pressing and drawing, while hot rolling is carried out at a temperature of 700°C to a degree of deformation of 0.5-2, continuous equal-channel angular pressing is carried out to a true degree of deformation 1-2 at a temperature corresponding to the development of continuous dynamic recrystallization with deformation aging, the drawing operation is carried out to a true degree deformations 1-2 at temperature, corresponding to the development of continuous dynamic recrystallization with deformation aging.

EFFECT: use of the proposed processing in the production cycle of the wire will make it possible to obtain a product with a complex of high characteristics, namely: strength, electrical conductivity, heat resistance and manufacturability.
