Fig.1 Strategies to design eutectic high-entropy alloys (EHEAs) (a) calculated pseudo-binary-phase diagram for FeCoNiCrNb x alloys[22] (b1-b4) microstructures of (CoCrFeNi)Mx EHEAs obtained by the simple mixing method[23] (c) empirical design criteria for EHEAs based on the relationship between valence electron concentration (VEC) and atomic size difference (δr)[25] (d) empirical design criteria for EHEAs based on the relationship between mixed enthalpy of solid solution (ΔHmixss) and VEC of solid solution (VECss) (IMC—intermetallic compound)[26]
