Thermodynamic assessment of the Ag-Zn system

A thermodynamic assessment of the Ag-Zn system has been done using a computerized CALPHAD (calculation of phase diagrams) technique. The liquid, α, β, η and var epsilon phases are described by a regular solution model, the γ phase by a four-sublattice model, and the ζ phase by a two-sublattice model, both based on considerations of their crystal structure and compatibility with the same phase in other systems. A set of parameters describing the Gibbs energy of the different phases is given and calculated phase diagrams are presented.
