| Abstract Scope |
Development of next-generation nuclear reactors, operating at higher temperature and under extreme environments, requires the development of new alloys for claddings, internals, and structural materials. Compositionally Complex Alloys (CCAs) are a relatively new class of alloys that has shown promising properties under extreme environments. However, considering the extremely large compositional space of CCAs, 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 CCAs processing method, using additive manufacturing and high-throughput ion irradiation at high temperature and high dose, coupled with automated characterization methods to measure void swelling and hardness evolution 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. |
