Abstract

The effect of severe plastic deformation and the subsequent impact of high hydrostatic pressure on the elastic and microplastic properties of Cu–0.2 wt % Zr alloy has been studied and analyzed. The influence of nanoporosity, which is formed in the process of equal-channel angular pressing and is fixed by applying hydrostatic pressure, has been evaluated.
