| Abstract Scope |
Refractory multi-principal element alloys (RMPEAs) are promising candidates for ultra-high temperature applications. The recrystallization behavior of these alloys is not yet well explored, and some have exhibited dynamic recrystallization atypical of BCC alloys, developing a necklace microstructure characteristic of low stacking fault energy FCC alloys. Understanding static and dynamic recrystallization behavior is crucial to developing thermomechanical processing pathways that lead to homogenous and reproducible mechanical properties. This study explores the recrystallization behavior of several NbTiZr-containing RMPEAs during and after hot- and cold-working. Deformation at various strain rates and temperatures with and without annealing heat treatments serves to develop an understanding of the extent of the recrystallized microstructure on these parameters. The knowledge gained from this study will allow us to develop models to predict recrystallization behavior, as well as the effects of recrystallization on microstructure, mechanical properties, and performance of RMPEAs. |
