Recent experiments by Yi et al.  and Ferroni et al.  show that microstructure of a material exposed to irradiation continues to evolve once irradiation has stopped. This phenomenon has significant practical consequences since on the one hand the high temperature recovery of irradiation damage is considered as one of the practical ways of restoring physical and mechanical properties of an irradiated material, and on the other hand, a robust mathematical treatment of dynamics of recovery is necessary for modelling microstructure formed under steady-state irradiation, where the observed microstructure results from the competition between generation of defects, and their thermal evolution and recovery. We focus on the mesoscopic scale of microstructural evolution, focusing on the treatment of self-climb and diffusion mediated climb of dislocations.
