Effect of Deformation Temperature on Formation of Ultrafine-Grained Structure in the Age-Hardenable Cu–Cr–Zr Alloy

The effect of the temperature of plastic deformation performed by equal channel angular pressing on the structure and physical and mechanical properties of the age-hardenable Cu–Cr–Zr alloy has been studied. Plastic deformation results in the formation of an ultrafine-grained structure in some regions with an average grain size smaller than 1 µm, a supersaturated solid solution decomposition, and the precipitation of disperse particles.
