Реферат: Numerical modeling of thermodynamic parameters of shock-wave loading of gold and alloys, containing gold as a component, has been performed using a thermodynamically equilibrium model. The model allows one to take into account the presence of a polymorphic phase transition in the material subjected to shock-wave action, which is essential for reliable modeling of both a pure material and alloys containing this material. Equations of state for two gold phases have been obtained using experimental data. Shock adiabats have been constructed for these phases in the pressure range of 1–1000 GPa. The pressure values on isotherms, as well as the values of heat capacity, entropy, and enthalpy along the gold isobar have been calculated. The results of the modeling have been compared with experimental data and with the results of calculations by other authors. Shock-wave loading of solid and porous gold–lead and gold–germanium alloys has been reliably described. The obtained equations of state can be useful in practical applications and in shock-wave experiments.
