Thermodynamic assessment of the Au–Pb system

The Au–Pb system has been thermodynamically assessed by the CALPHAD method. The excess Gibbs energies of the solution phases were modeled assuming random mixing of components, while the three intermetallic phases were described as stoichiometric compounds. Based on the experimental phase diagram and thermochemical data, a set of self-consistent parameters describing all phases in this system has been obtained.
