| Abstract Scope |
Refractory high entropy alloys (RHEAs) have unique properties, including high strength and irradiation resistance in elevated temperature environments. RHEAs are possible candidates for salt facing structural materials for the molten salt reactor (MSR), but there are few studies examining the corrosion resistance and irradiation resistance of RHEAs in an MSR-like environment.
This work highlights a candidate RHEA, sintered AlMoNbTiZr. This material was subjected to high radiation doses at reactor temperatures, then characterized using microscopy techniques. Ion irradiated samples and non-ion irradiated samples were placed in Cl and F molten salt environments, to observe how ion irradiation changes the molten salt corrosion resistance of the RHEA.
This work presents progress towards understanding how high entropy properties and refractory metal composition affects radiation and molten salt corrosion resistance in compositionally complex MSR candidate materials, as well as advancing the general understanding of ion radiation effects on molten salt corrosion resistance. |
