Abstract
The effect of severe plastic deformation on the kinetics of second phases in a dispersion-strengthening Cu-Cr-Zr alloy is investigated. The observed set of phenomena indicates that during SPD processing there occurs a complex interaction between deformation mechanisms and the processes of dissolution and precipitation of second-phase particles in the copper matrix, influencing structure refinement and resulting in a change of the particle sizes and their distribution, and consequently, the material’s strength.
