High-entropy alloys (HEAs) are promising candidates for generation IV fission & fusion energy, offering high melting points, high strength and irradiation tolerance. However, their selection & design remains a major challenge with the vast size of the composition design space & predictive capability. In this work, we explore several million of element combinations using the Alloy Search and Predict (ASAP) software, which screens for HEAs candidates with single-phase stability at high temperature. Within the ASAP HEA screening, we further select for HEAs with lower thermal neutron absorption cross section. These HEAs have refractory metals (RM) as their main constituents providing great potential for application in extreme environments. These newly identified RM-HEAs have been experimentally product, their microstructure & properties analysed by experimental techniques and compared with phase predictions of ASAP and CALPHAD.
