  • Three new elements: Co, Dy, and Tb; now a 9 elements framework
  • 35 new phases (total of 54)
  • The gas description is included

  • 21 new assessed binary systems (for a total of 36); 18 new assessed ternary systems (for a total of 29):

    • Added Co: Assessed or tentatively assessed 8 binary systems(B-Co, Ce-Co, Co-Fe, Co-Dy, Co-La, Co-Nd, Co-Pr, Co-Tb) and 14 ternary systems (B-Ce-Co, B-Co-Fe, B-Co-La, Ce-Co-Fe, Ce-Co-La, B-Co-Dy, B-Co-Nd, B-Co-Pr, B-Co-Tb, Co-Fe-La, Co-Fe-Nd, Co-Fe-Pr, Co-Fe-Tb, Co-Nd-Pr).

    • Added Dy: Assessed or tentatively assessed 6 binary systems (B-Dy, Ce-Dy, Dy-Fe, Dy-Nd, Dy-La, Dy-Pr) and 2 ternary systems (B-Dy-Fe, Dy-Fe-Nd).

    • Added Tb: Assessed or tentatively assessed 7 binary systems(B-Tb, Ce-Tb, Dy-Tb, Fe-Tb, La-Tb, Nd-Tb, Pr-Tb) and 2 ternary systems (B-Fe-Tb, Dy-Fe-Tb).

  • The surface tension was re-assessed based on the Redlich-Kister-Muggianu (R-K-M) sub-regular solution model.
