| Abstract Scope |
Two decades after their discovery, high-entropy alloys continue to attract strong interest in the international community. Among the unresolved fundamental questions, the one leading to the understanding of the existing deformation processes in these compositionally complex alloys is exciting but remains widely debated. In this context, the talk will provide an overview of the current analysis and understanding of the deformation processes in such alloy with body-centered cubic structure above room temperature. Emphasis will be placed on the possible origins of the strength plateau observed in several refractory solid solutions. A special focus will also be made on impurities, whose role in dislocation mobility—and thus in mechanical behavior—is often overlooked. Emerging evidence suggests that they may play a key role in the temperature-dependent strength of these alloys. |
