Resumo

The character of dislocation propagation and arrest during activationless motion in alkali halide crystals under a pulsed load is considered. A model of structural transformation of impurity complexes caused by spatial reorientation of bound excitons under the action of external factors is proposed. In the framework of this model, it is possible to explain the well-known effects of photoplasticity, magnetoplasticity, and activationless motion of dislocations at the front of a loading pulse.
