Abstract Scope |
Deployment of next-generation nuclear reactors, operating at high temperature and under extreme environments, requires the development of new alloys for claddings, internals, and structural materials. They are required to have excellent mechanical properties even after being irradiated to high fluences. HEAs have shown promising properties under extreme environments. However, considering the large compositional space of HEAs, manufacturing, characterizing and studying the effects of irradiation on their properties using conventional methods is not compatible with the deployment timeline of these reactors. In this study, we have combined innovative high-throughput HEAs processing method, using additive manufacturing, and high-throughput ion irradiation at high temperature, coupled with automated characterization methods to measure void swelling and hardening of a wide composition space of the Cr-Fe-Mn-Ni system as function of dpa. Preliminary results and importance ranking order based on Cr-Fe-Mn-Ni properties and void swelling/hardening performance metrics will be presented using a Random Forest Regressor algorithm. |
