A theoretical model that describes the implementation of high ductility in high-pressure torsion (HPT) processed ultrafine-grained aluminum subjected to annealing and additional HPT deformation, is suggested. In the framework of the model, the plasti

A theoretical model is proposed that describes the hardening mechanism of ultrafine-grained aluminum obtained by high pressure torsion after low-temperature annealing. Within this model, the hardening is due to the successive transformation of the gr

A special physical mechanism for the formation of nanoscale deformation twins in nanocrystalline and ultrafine-grained materials is suggested and theoretically described. The mechanism represents the cooperative emission of partial dislocations from
