Abstract Scope |
Multi-principal element alloys (MPEAs) have been proposed as potential structural material candidates for next-generation nuclear reactors because of their notable mechanical properties and environmental resistance. However, the effects of irradiation on the microstructural and chemical evolution of these alloys are still not fully understood. Grain boundaries are of particular interest due to their susceptibility to radiation-induced segregation (RIS), which by altering their chemistries can negatively impact the resistance of the materials to stress-corrosion. Focusing on the impact of alloy chemistry and the role of single elements on RIS, we systematically characterized the RIS behavior at grain boundaries in three ion-irradiated single-phase FCC Fe-Ni-Cr-Co-Mn based alloys. The results provide insights into the effects of dose, temperature, and alloy composition on RIS. |
