Physical models are developed for the evolution of the dislocation density in metals subject to irradiation at elevated temperatures. Two basic processes ara shown to account for the experiment observations: the generation of dislocation line length takes place by the Bardeen-Herring mechanisms, whereas diiocation loss can be described in terms of dislocation dipole ann~lation. Only two miuostructural parameters, namely the mesh length and the bias variance, need to be introduced and adjusted in order to reproduce the experimental observations on dislocation evolution in austenitic stainless steels.

At present no dislocation theories can answer the above question, and we suggest that a modified interpretation of K, is dispensable to account for the yielding behavior of pressurized iron. Another question is left unanswered which is about the result of coarse grained specimens. The increase of
