Abstract
Mobile grain boundaries (GB) may have specific interactions with radiation-induced defects compared with static GBs. In this paper, we consider the GB-defect interactions for the {1 1 2} GB that performs shear coupled grain boundary migration mediated by its glissile disconnections. The conservative motion of this GB facilitates the interaction with radiation-induced defects both, mobile and sessile. While mobile defects interact by diffusing to GBs, sessile defects are approached by moving GBs....
