Compositional phase stability in medium-entropy and high-entropy Cantor-Wu alloys from an ab initio all-electron Landau-type theory and atomistic modeling

“…Fe in particular has a large local moment associated with it, and we expect the nature of predicted order in this material to be different between FM and PM states. Indeed, in an earlier work on Galfenol, a binary Fe-based alloy, we found that the nature of magnetic order significantly affected the nature of compositional order [77]. We only model the PM state in this work because the Curie temperature is around 120K [18,33,78], well below the temperatures at which these materials are annealed [60].…”

Controlling microstructure and magnetic responses in FeSiB system under magnetic or mechanical inputs

“…Both of these Fe-Si phases possess large miscibility and can tolerate significant nonstoichiometry. While both the α and α'' phases show BCC-like lattice symmetry, they differ in terms of the degree of chemical ordering (Marchant et al, 2021). Figure 2-7 shows schematics of the crystal structure for these two phases with chemical composition Fe1-xSix.…”
