| Abstract Scope |
Multi-principal element alloys (MPEAs) are of interest to the nuclear community for their observed resistance to microstructural damage under irradiation. Robust experimentation to relate MPEA composition to irradiation resistance and corrosion performance – critical properties in nuclear environments – is lacking, and these properties are poorly understood together. To accelerate experimental study of MPEA irradiation and oxidation, high-throughput synthesis, irradiation, corrosion, and characterization techniques have been employed in this work. This was achieved through high temperature high-throughput irradiation of additively manufactured MPEAs. Hardening and void swelling of irradiated samples were measured via automated nanoindentation and machine learning assisted analysis of SEM images. Pre- and post-irradiation corrosion behaviors were analyzed using x-ray diffraction and glow discharge optical emission spectrometry. Trends in the experimental data relating irradiation induced hardening, void swelling, and oxidation behaviors to composition have been analyzed using different machine learning approaches. |
