摘要

Annealed oxygen-free and tough-pitch copper samples have been processed by equal-channel angular pressing (ECAP) by route Bc The samples included 8×8 mm section pieces and a 40 mm diameter bar. Thermal stability was assessed based on the changes in the standard mechanical properties (conventional yield strength, tensile strength, elongation, proportional elongation and contraction) after annealing at different temperatures for 1 hour.rnThermal stability of the same grade of material has been found to be different for different batches and to depend on the structural conditions of deformed material. The zone of thermal stability for copper of the two grades of interest does not depend on the material's chemical composition.
