摘要：

Thermodynamic optimization of the Ga-Li binary system was carried out using the CALculation of PHAse Diagrams (CALPHAD) method. Ga14Li3, Ga7Li2, Ga8Li3, Ga9Li5, and Ga4Li5 were treated as stoichiometric compounds, while a solution model was used to describe the liquid, ORTHORHOMBIC_CMCA (Ga), and BCC_A2 (Li) phases. The intermetallic compounds GaLi, Ga2Li3, and GaLi2, which have homogeneity ranges, were treated using a two-sublattice model. The results of the calculations based on thermodynamic modeling are in good agreement with phase diagram data and experimental thermodynamic values.
