Abstract
The effect of high-pressure torsion (HPT) deformation on the structure and hardening of three-layered hybrid steel/copper/steel material and its components has been studied in this work. The HPT of the three-layered steel/copper/steel blank results in the formation of a strong boundary between layers, which is mainly smooth, and in an increase in their strength. However, no maximally possible values of microhardness of the outer steel layers of the hybrid are reached because of the absence of ultrafine-grained structure in them.
