Abstract Scope |
Phase equilibria plays a central role in the growing field of high-entropy alloys (HEAs) and complex, concentrated alloys (CCAs). The majority of HEAs and CCAs are reported in the as-cast condition, a growing number are characterized after some amount of homogenization, and a few experimental studies measure the phases present after long-term anneals that may approximate equilibrium conditions. These latter studies will be reviewed in this presentation, and results will be compared with appropriate commercial alloy families, especially regarding the extended gamma loop in the Fe-Ni-Cr system and the solid solution alloys common in refractory metals. The important role of computed phase diagrams will also be discussed. |
