Irradiated materials exhibit complex microstructures due to complex defect interrelations and configurations from pre-existing defects and those induced or modified by combined effects of irradiation and temperature. To mitigate defects such as swelling, irradiation-induced segregation, and hardening, a low current density electropulsing process was used to study structure-property-processing relationship in FeCrAl alloy. The results show an improved microstructure, without compromising the mechanical properties. This is attributed to the pronounced dislocation generation, regeneration, and clustering as well as defect healing. Ultimately, there is a reduction in the residual strain and a significant increase in the intrinsic strength.
