Abstract—

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. The fraction of the supersaturated solid solution which is decomposed is shown to increase with increasing deformation temperature. The density of microshear bands, the dislocation density, and the fraction of high-angle boundaries and the ultrafine-grained structure increase with increasing volume fraction of disperse particles.
