Abstract

The authors analyze the effect of the accumulated strain during severe plastic deformation as well as the temperature and aging time on the physico-mechanical properties of low-alloyed chromium-zirconium bronze Cu-1Cr-0.08Zr. The following SPD processing techniques were employed in the work: high-pressure torsion (HPT) and equal-channel angular pressing (ECAP). As a result of the investigation there have been revealed the most reasonable regimes of thermomechanical treatment, leading to the maximum increment in mechanical properties, while preserving a high level of electrical conductivity.
