摘要
The melting temperature, the jumps of volume, enthalpy and entropy at the melting point, the isothermal compressibility, the thermal expansion coefficient, the heat capacity at constant volume, the Gruneisen parameter, the Debye temperature, the electrical resistivity, the thermal conductivity, and the thermal diffusivity for defective and perfect f.c.c. metals are studied by combining the statistical moment method (SMM), the limiting condition of the absolute stability of the crystalline state, the Clapeyron-Clausius equation, the Debye model, the Gruneisen equation, the Wiedemann-Franz law and the Mott equation. Numerical calculations are carried out for Au under high temperature and pressure. Calculated melting curve of Au is in a good agreement with experiments and other calculations. Obtained results are predictive and orient towards new experiments.
