The Au-Cu-Sn system was thermodynamically assessed with CALPHAD method in order to obtain an optimized and consistent thermodynamic description. It was found that the resulting thermodynamic optimization is in good agreement with the limited experimental data available, except for the Au rich part of the ternary isothermal section at 360 oC.

The Gibbs energy of formation for the three ternary compounds A, B, and C were obtained, and the ternary interaction parameters for fcc and hcp phases were assessed. All of the calculations were performed using PANDAT software.
