| Abstract Scope |
Dating back to an outstanding idea put forward in 2004, the past decade witnessed the emergence of multi-principal element alloys (MPEAs) where three or more elements are mixed equally or near equally into single- or multi-phase systems. The highly tunable properties of these alloys allow them to perform better than their conventional counterparts for critical structural applications, especially under extreme conditions. In this talk, the optimization of MPEAs’ properties at either low or high temperature ranges will be covered, and related strengthening and deformation mechanisms will be summarized. Moreover, the latest challenges and efforts for searching MPEAs that possess superb mechanical properties across a broad range of temperatures will be presented. Some unique temperature-dependent properties of MPEAs will also be described. In the end, guidance for future development of MPEAs at cryogenic-to-elevated temperatures will be provided. |
