Al–4 wt% Cu alloy specimen was subjected to loading by spherical converging shock waves. A detailed analysis of recovered sample was performed using optical metallography, scanning and transmission electron microscopy, and microhardness measurements along the radius. The high-rate plastic deformation of the alloy under the loading conditions was found to occur via slip, and, in medium and deep layers, it also occurs via the formation of localized deformation bands and deformation vortices.
