Abstract
The Gd–Bi and the Ho–Bi systems were thermodynamically assessed by CALPHAD (CALculaton of PHAse Diagram) approach based on the available experimental data including thermochemical properties and phase equilibria. The formation enthalpies (at 0K) of the compounds of the Gd–Bi and the Ho–Bi systems were calculated by the first-principles method and used in the present thermodynamic optimization. The excess Gibbs energies were formulated with the Redlich–Kister polynomial. The intermetallics, Gd5Bi3, Gd4Bi3, GdBi, GdBi2, Ho5Bi3 and HoBi, were treated as stoichiometric compounds. A good agreement between the calculated results and the experimental data was obtained.
