(a) Alloy entropy of mixing versus solid solution entropy of mixing, and (b–d) relationships of the solid solution parameter Ω with the solid solution (b) enthalpy of mixing, (c) parameter δ and (d) parameter Δχ. Red data CC/HE Nbss alloys JN2-AC, TT4-AC, TT7-AC, EZ8-AC, TT6-AC, ZF9-AC, TT5-HT, blue and brown data “conventional” Nbss, blue data AC and HT alloys JN3 and JN4, and HT alloys YG8, YG10, TT4, TT7, brown data AC alloys YG8, YG10, AC and HT alloys YG11, KZ5, JN1 and ZF6, and HT alloys KZ6, JG3 and TT8. Green triangles for B containing alloys, yellow squares for RCCAs. For nominal alloy compositions and references see the Appendix A. In (a) for all data R2 = 0.9019, blue and brown data linear fit with R2 = 0.9127, brown data linear fit with R2 = 0.8854, in (b) R2 = 0.8557 is for linear fit and R2 = 0.9757, R2 = 0.8612 and R2 = 0.8764 are for parabolic fit, the latter value is for all the data, in (c) all the R2 values are for linear fit of data, in (d) all the R2 values are for parabolic fit, and R2 = 0.7233 is for all the data. HE Nbss in TT4-AC.
