| Abstract Scope |
High-entropy alloys (HEAs) are promising candidates for generation-IV fission and fusion energy, offering high melting points, high strength and irradiation tolerance. However, its selection and design remain a major challenge within the vast size of composition and predictive capability. In this work, we explore several million combinations using the Alloy Search and Predict (ASAP) software, which screens for single-phase stability at high temperature. Further, we select HEAs with low neutron absorption cross-section. These HEAs have refractory metals (RM) as their main constituents providing great potential for application in extreme environments. A group of RM-HEAs is here produced and studied by diverse correlative mapping characterization techniques. This methodology allowed access in the same area to individual phase properties such as chemical composition, crystal structure, grain orientation, thermal conductivity, hardness and elastic modulus. These complimentary mappings are optimal for a quick and thorough characterization and especially useful for optimizing the alloy design. |
