Abstract

A thermodynamic database on the phase equilibria of the copper base alloys, including Cu-X binary system and Cu-Fe, Cu-Ni, Cu-Cr, Cu-Co, Cu-Mo and Cu-W base ternary systems were developed by the calculation of phase diagrams (CALPHAD) method. The Gibbs free energies of the solution phases were described by subregular solution model with the Redlich-Kister equation, and the Gibbs free energies of the intermetallic compounds were described by sublattice model. The thermodynamic parameters describing the Gibbs energies of different phases were evaluated by optimizing the experimental data of phase equilibria and thermodynamic properties. The present thermodynamic database can provide much information, such as stable and metastable phase equilibria, phase fraction, liquidus projection and various thermodynamic quantities, which is expected to play an important role in the design of copper base alloys.
