Multicomponent high-entropy Cantor alloys
Brian Cantor,Brian Cantor +1 more
TL;DR: A review of multicomponent high-entropy Cantor alloys can be found in this paper, where the authors describe the extensive range and complexity of multic-component phase space, including the prevalence of single (or relatively few) phases and the paucity of intrinsically new multic-component compounds.
