| Abstract Scope |
Compositionally complex alloys (CCAs) are an area of interest as potential structural alloys in the nuclear community due to their observed resistance to microstructural damage under irradiation. This irradiation response has been explored in a narrow set of compositions, and knowledge on the impact of compositional effects within the CCAs in general is relatively limited. To provide a broad look at CrFeMnNi quaternary CCA space, the high-throughput beamline at the University of Wisconsin’s Ion Beam Lab has been employed to study 100 additively manufactured samples with irradiations up to 150 displacements per atom at 600 °C. As standards for comparison, SS316 and alloy 617 were irradiated to the same conditions. Focused ion beam and scanning electron microscopy characterization of void swelling and nanoindentation to study irradiation-induced hardening have been employed to quickly select compositions of interest for more thorough analysis via transmission electron microscopy. |
