Dislocation multiplication. I. On the theory of dislocation multiplication

The quantitative theory of a double cross‐slip mechanism is proposed, the main equations of which are expressed in terms of the activation parameters of dislocation mobility. This allows to take into account the effect of the thermodynamic conditions (temperature and hydrostatic pressure) on the dislocation multiplication. It is noted that when initiating new dislocation loops by a double cross slip mechanism the motion of a screw dislocation component in the slip plane is not obligatory. [Russian Text Ignored].
