Thermodynamic assessment of the Cu-Sn system

Abstract

A thermodynamic assessment of the Cu-Sn system has been carried out using the CALPHAD method. The Gibbs energies of individual phases in the system have been modelled employing the regular solution type model and the two-sublattice model. A set of self-consistent model parameters has been obtained taking into account phase equilibria and thermodynamic information available in literature. The measured phase diagram and thermodynamic quantities were satisfactorily reproduced with the optimized model parameters.
