Zentropy theory for accurate prediction of free energy, volume, and thermal expansion without fitting parameters

Figure 2. Temperature-volume phase diagrams with isobaric volumes at various pressures of (A) Ce and (B) Fe3Pt. The volume (V) is normalized to their respective equilibrium volume ($$ \mathrm{V}_\mathrm{N} $$) at atmospheric pressure and room temperature. The highlighted regions by the pink open diamonds are illustrated for anomaly behaviors in terms of more positive thermal expansion for Ce and negative thermal expansion for Fe3Pt. Below the critical point marked by the green open circle, the single phase is no longer stable and decomposes into a two-phase mixture in the region of a miscibility gap. Symbols are from various experimental measurements in the literature[19]. Reproduced with the permission of Ref.[19] Copyright © 2014, The Authors.
