Abstract Scope |
Refractory Complex concentrated alloys (RCCAs), which also include refractory high-entropy alloys, are an innovative class of materials that exhibit great potential for future use in high temperature, structural applications. Their compositional complexity has been reported to provide a unique landscape for the design of alloys with a variety of superior properties. In particular, the high concentration of alloying elements in RCCAs enables inherent oxidation resistance that is not readily accessible in conventional, dilute refractory alloys. This talk outlines recent developments regarding our understanding of the oxidation mechanisms in these systems and reviews particular strategies being explored in the community. RCCA oxidation mechanisms are discussed relative to classic oxidation theory and existing predictive models. Current knowledge gaps and critical future design considerations are also addressed. |
