    Abstract
  • An equation-of-state (EOS) calculation model was presented for a multi-component mixture by assuming that all components of the mixture are in a locally thermodynamic equilibrium state, which means that they are isothermal and isobaric, and that the sub-volume of each component is additive. Thermodynamic quantities of the mixture, such as internal energy, pressure, constant-volume specific heat, pressure coefficient and isothermal sound speed, can be constructed with the EOS of each component. Based on this model, we calculated the EOS of a 4-component tungsten alloy, which is remarkably consistent with the result achieved from the wide-range equation of state.
