  • Seven (7) new elements added to the database to align with the thermodynamic database: Nb, Pt, Rh, Ru, Ta, V, and W. Now it is a 19 element framework.
  • Parameters for the new elements Nb, Pt, Rh, Ru, Ta, V, and W in the liquid phase are estimated using the Modified Sutherland equation.
  • Twenty-one (21) newly assessed binary systems for BCC_A2 phase (total 38): Al-Nb, Cr-Nb, Cr-Ta, Fe-V, Hf-Nb, Hf-Ta, Mn-V, Mo-Nb, Mo-Ta, Mo-W, Nb-Ta, Nb-Ti, Nb-V, Nb-W, Nb-Zr, Ta-Ti, Ta-W, Ta-Zr, Ti-V, Ti-W, and V-Zr.
  • One (1) newly assessed binary system for FCC_A1 phase (total 8): Al-Pt
  • Seven (7) newly assessed ternary systems for BCC_A2 phase: Ti-Al-Nb, Ti-Cr-Nb, Ti-Mo-Ta, Ti-Nb-Ta, Ti-Nb-V, Zr-Ta-Nb, and Zr-Ti-Nb.
