Title: Effect of high-temperature irradiation on the local environment of the various atomic species in oxide dispersion strengthened-concentrated solid solution alloys

Abstract: The demand for high-temperature radiation-resistant materials has intensified with the rapid evolution of clean energy technologies such as nuclear power. However, structural material discovery for such applications is a challenge due to the extreme service conditions. The current research attempts to address this issue and explores the novel oxide dispersion-strengthened (ODS) alloys. Our previous work showed irradiation-induced chemical segregation at grain boundaries for ODS-NiCoFeCr; while ODS-NiCoFe and ODS–NiCoCr are relatively irradiation damage-resistant. The proposed experiments will conduct atomic scale imaging and spectroscopy to elucidate the possible mechanisms of such effects. The hypotheses include vacancy-assisted Cr migration in ODS-NiCoFeCr, chemical short-range ordering of Cr-Ni and Cr-Co in ODS-NiCoCr, and the absence of both these phenomena in ODS-NiCoFe.
