Segregation of nickel in grain boundaries (GBs) in the Fe-Cr-Ni alloy induced by radiation (RIS) or plastic deformation (DIS) has been studied in the framework of a model which considers the generation of point defects, their mutual recombination, and absorption in GBs. It has been demonstrated that...
