| Abstract Scope |
High entropy oxides have been developed leveraging the chemical complexity of these materials. Extensive research has focused on the entropic stability of single-phase solid solutions and consequential behavior. High entropy oxides have also been shown to exhibit complex responses to mechanical and thermal stimuli, such as the formation of extensive dislocation networks and decomposition into multiphase states. Such responses lead to the formation of new interfaces and microstructural features that can significantly alter the functional performance of these materials. These features are expected to also alter the stability of high entropy oxides under harsh environments. While our current understanding of these phenomena is still rather limited, this presentation will review and highlight important findings on the formation of dislocations and multiphase states in high entropy oxides, the interfaces and microstructures that form as a result, and the consequential effect on mechanical and electrical behavior. |
