Abstract According to characteristic crystal theory of alloy phases established on the statistic thermodynamics and electronic theory of metals,a systematic analysis has been conducted on the Au-Cu system. The interaction equations of characteristic properties (energy and volume),electronic structures and their changing characters of characteristic atoms in the Au-Cu alloys have been determined. The theoretical values of heat of formation, mixing Gibbs free energy and lattice constant as a function of concentration are in good agreement with the experimental values.XIE Youqing, professor, Department of Materials Science and Engineering, Central South University of Technology, Changsha 410083

Key words: Au-Cu alloy electronic structure atomic configuration heat of formation lattice constant
