High-rate deformation resistance and fracture resistance under the shock-wave loading of A5083 aluminum alloy have been investigated. The alloy was before-produced in two structural states by high-pressure torsion and dynamic pressing. The electron microscopy methods showed that the formed submicrocrystalline structures differ in a grain-subgrain size, dislocation density, a proportion of high-angle and low-angle boundaries. It was established that for the same grain size the submicrocrystalline alloy processed by megaplastic deforming had better dynamic properties than the alloy after dynamic pressing. However the alloy processed by dynamic pressing had higher spall strength.
