摘要：

Tough-pitch copper M1 is studied after deformation by the method of equal channel angular pressing (ECAP) in a die with parallel channels with the use of cryogenic cooling in liquid nitrogen. Comparative analysis of the properties of the copper after the ECAP with cooling in liquid nitrogen and at room temperature is performed. Special features of formation of ultrafine-grained structure in quenched copper M1 under the ECAP in the die with parallel channels are determined. The role of cooling with liquid nitrogen after the ECAP is shown to be positive from the standpoint of deceleration of the processes of static and dynamic recrystallization and improvement of the combination of the mechanical properties of the copper.
