| Abstract Scope |
Complex Concentrated Alloys (CCAs) represent a transformative approach to alloy design that allow for the precise tuning of mechanical, thermal, and chemical properties, rendering CCAs highly attractive for nuclear energy systems. In particular, Refractory CCAs—formulated with elements such as Mo, Nb, Ta, W, and V—offer excellent high-temperature creep resistance and demonstrate strong compatibility with alkali liquid metals, which are relevant for advanced reactor coolants. These alloys have been systematically designed and optimized using computational thermodynamic tools like CALPHAD to predict phase stability and guide compositional selection. Extensive multiscale microstructural characterization has confirmed the formation of single-phase body-centered cubic (BCC) structures with promising thermal and mechanical stability. To assess their suitability in molten salt reactor environments, selected RCCAs were subjected to molten salt environment at various temperatures, aiming to elucidate degradation mechanisms in fluoride and chloride salt environments. |
