Abstract Scope |
High entropy alloys are innovative materials that have demonstrated great promise for future use in high temperature environments. Their chemical complexity offers extended versatility in balancing performance characteristics across mechanical, thermal and environmental domains. However, oxidation resistance remains a significant design challenge, especially in the refractory realm, as conventional refractory alloys are well-known to exhibit poor oxidation resistance. Nevertheless, refractory high entropy alloys have been reported to form more favorable complex oxide species that do not readily form in conventional/dilute alloys and offer a substantial enhancement of oxidation resistance in some cases. This talk highlights the application of advanced electron microscopy to interrogate the complex oxide scales that form on these alloys and will discuss the implications of oxidation on mechanical response. Key technical gaps and future opportunities will be presented. |
