Abstract
The thermodynamic properties of the stable and metastable phases of theCu−Au, Ag−Au, andCu−Ag systems have been calculated in the representation of the many-body interatomic interaction potential within the framework of the model electron-density functional method. The calculated values of the thermodynamic properties are in good agreement with experimental data and help explain the laws of alloy formation in the given systems. Factors that affect the magnitude of the tetragonal distortion of theL1 0 structure of equiatomic alloys have been investigated. The possibility of a transition by the Bayne scheme from theL1 0 structure toB2 for alloyCuAu upon application of an external uniaxial [001] stress is discussed.
