Thermodynamic database of the phase diagrams in copper base alloy systems Original Research Article

A thermodynamic database on the phase equilibria of the copper base alloys, including Cu–X binary system and Cu–Fe, Cu–Ni, Cu–Cr base ternary systems has been developed by the Calculation of Phase Diagrams (CALPHAD) method. The thermodynamic parameters describing Gibbs energies of the different phases have been evaluated by optimizing 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 and so on, which is expected to play an important role in the design of copper base alloys.
