Application of statistical moment method to thermodynamic properties of metals at high pressures

摘要: The moment method in statistical dynamics is used to study the thermodynamic properties of metals taking into account anharmonicity effects lattice vibrations and hydrostatic pressures. explicit expressions constant, thermal expansion coefficient, specific heats C v p cubic (fcc) are derived within fourth order approximation. quantities Al, Au, Ag, Cu, Pt calculated as a function pressure, they good agreement with corresponding experimental results. effective pair potentials work well for calculations transition noble metals, compared those s -valence metals. For obtaining better like it required at least use more sophisticated electronic many body potentials. In general, has been shown that vibration play dominant role determining thermodynamic...
