Effect of high-rate deformation on the structure, the properties, and the thermal stability of copper alloyed with chromium and zirconium

Resumo

The deformation behavior and the properties of copper alloyed with chromium and zirconium (0.04–0.14 wt %) are studied during high-rate deformation (~10⁵ s^–1) by dynamic channel angular pressing (DCAP). The sequence of the decomposition of the α solid solution of copper accompanied by the precipitation of second-phase nanoparticles and recrystallization in annealing (aging) is determined. The influence of DCAP and aging on the mechanical and physical properties of the copper alloys is investigated.
