Recent results of computer modeling of severely plastically deformed (SPD) pure metals are presented. The simulation is carried out in terms of kinetic diclocation approach. The questions related to the influence of the high-pressure torsion and equal channel angular pressing on the structure evolution at SPD are discussed.
