| Summary: | By means of CALPHAD approach, thermodynamic assessments of the Mg-Pb and
Mg-Bi systems were carried out based on the available experimental data
including thermodynamic properties and phase equilibrium data. The liquid
phase was described with both the substitutional solution model and the
associate model, and two sets of self-consistent thermodynamic parameters for
the Mg-Pb and Mg-Bi systems were obtained, respectively. It was found that
the associate model can account for the experimental data more satisfactorily
than the substitutional solution one, especially for the liquid phase with
the short-range order behavior. |
