Изучение свойств ГЦК-Au в широком диапазоне температур и давлений

The properties of the FCC gold crystal were calculated using an analytical method (without computer modeling) in temperature range: T = 10 – 1337 K and pressures: P 0 110 GPa. following calculated: state equation, Debye temperature, first second Gruneisen parameters, elastic modulus (BT), thermal expansion coefficient (p), isochoric (Cv) isobaric (Cp) heat capacity, specific surface energy. Derivatives these also have been both by along three isobars pressure isotherms. obtained results showed good agreement with other authors results. It was shown that there is a certain TB which product pBT does not change during compression. At > TB, function increases, at < it decreases increase pressure. For FCC-Au has received =132 K. Показано, что изотермы производной модуля упругости по давлению B(P) пересекаются в точке: 21.58 GPa, 7.43. isotherms baric derivative intersect point: increasing temperature. isotherm capacity Cv(P) minimum, Cp(P) minimum maximum. Based on dependencies, some approximations, are used to calculate under high P-T conditions, analyzed.
