ABSTRACT

The kinetics of dislocations is studied by means of computer simulation at different severe loadings. It is found that the dislocations can have a few (at least, two) different structural states. The localized dislocations with core shape as ”micropore” play important role in formation of large curved grain boundaries, and, as a consequence, in formation of fine grains. Saltatory alternation of elastic and non-elastic stages of deformation is revealed too. At shear loading in view of special kinetics the system would have to accumulate whole set of localized dislocations leading to formation of new boundaries and fine grains.
