Abstract Scope |
Multi-principal element alloys (MPEAs) have been proposed as candidate materials for nuclear applications due to their superior mechanical properties and corrosion resistance. Yet, the literature concerning the microstructural and chemical changes in these alloys upon irradiation remains limited. Therefore we focus here on the effects of irradiation near and at grain boundaries in MPEAs, with an emphasis on radiation-induced segregation. To this end, a series of CrFeNi/based MPEAs was irradiated using heavy ions. The analysis and comparison of the chemical composition of the grain boundaries in the irradiated and non-irradiated alloys provide insights into the behaviors of point defects in different alloy chemistries. |
