Abstract Scope |
As advancements are made in nuclear systems, fusion reactors, space exploration, etc., there is a prevalent need for a radiation resistant material that can withstand mechanical extremes. High Entropy Alloys (HEA) are a strong contender for this role as they contain a high density of grain boundaries (GB) which enhances radiation tolerance and great material properties. The mechanisms of radiation damage tolerance at GBs in HEAs are not well surveyed or understood. To address this knowledge gap, we simulate high dose radiation damage in two HEA systems of different compositions (FeNiCrCoAl and NiCrCo) and analyze the composition and GB character dependence of the steady state irradiated microstructure. This analysis can provide insight into how HEA composition and microstructure can influence radiation damage evolution. |
