NSUF 22-4400: Ion Irradiation and Characterization of FeCrAl Oxide Dispersion Strengthend Alloy Manufactured via Laser Powder Bed Fusion
FeCrAl alloys are accident tolerant fuel (ATF) claddings due to superior oxidation/corrosion resistance and high induced swelling resistance at the high-temperature steam environments and/or high irradiation. Additive manufacturing was used (laser powder bed fusion) to manufacture net shape FeCrAl ODS alloy with reduced supply chain and production steps. Microstructure and mechanical properties of produced FeCrAL ODS are characterized and revealed the presence of nanoparticles enriched in Y-Al-O in the matrix. Microhardness values were superior to the wrought counterparts. Additively manufactured FeCrAl ODS alloy will be ion irradiated and characterized to identify the irradiation performance of such alloy.
