چکیده انگلیسی
The Au-Ga binary system was assessed thermodynamically using the CALPHAD method through Thermo-calc®Â software based on the critical review of the available experimental data from the published literature. The solution phases including liquid, fcc(Au), D024 and orthorhombic(Ga) are modeled by the substitutional solution model and their excess Gibbs energies are expressed with the Redlich-Kister polynomial. The intermetallic compounds, β- Au7Ga2, βâ²- Au7Ga2, γ- Au7Ga3, AuGa and AuGa2 are treated as stoichiometric compounds. A set of self-consistent thermodynamic parameters obtained finally to describe the Gibbs energies of various phases in the Au-Ga binary system can be used to reproduce well the reported phase equilibria and thermodynamic properties data.
