Abstract

The kinetics of dislocations is studied with computer simulation at loadings of different intensity. It is established that the dislocations have a few different structural states. The dislocations "with the micropore" play important role in the formation of large curved boundaries, and, as a consequence, in the formation of fine grains. Alternation of elastic and inelastic strain stages is established too. At shear loading, in view of special kinetics, the system would have to accumulate the whole set of dislocations leading to the formation of new boundaries and fine grains.
