Abstract
Plastic structure formation in AD1 aluminum has been studied experimentally and theoretically using a physical phenomenological model of cyclic and nearly cyclic plastic deformation with large strain intensities accumulated in one and several cycles. Based on the results obtained, the proposed model of the process was verified, the concept of severe plastic deformation was refined, its role in structure formation was investigated, and the existence of a limit of grain refinement during deformation processing of metals was shown.
