Abstract Scope |
Refractory high entropy alloys are plagued with limited oxidation resistance at high temperatures, despite their promise for use in aerospace and energy-related applications. Much research has been dedicated to additions of traditional passivating elements, such as Al, Si, and Cr, to refractory alloy systems, however the oxide scale formed in these systems is not continuous. Here we present a path toward continuous scales based on epitaxial interfacial design and present work in traditional approaches as well as insight into key interfacial relationships in oxide scales that promote continuity. Ultimately, this work provides a foundation for high temperature use of refractory high entropy alloys with oxidation mitigation. |
