The effect of high strain-rate deformation (HSRD) on microstructure and crystallographic texture of Сu in an annealed coarse-grained (CG) state and ultrafine-grain (UFG) state, developed in the result of equal-channel angular pressing (ECAP) has been analyzed here. The results of microstructure and texture researches point out that HSRD leads to the decrease of the grain size, the increase of the elastic root-mean-square distortions, the increase of the dislocation densities and the volume share of the twins both in CG and in UFG states.
