Wide-range multi-phase equations of state for metals

The generalization of available experimental and theoretical information is given in the form of a multi-phase wide-range equation of state (EOS). The semiempirical EOS model accounts for solid, liquid, gas and plasma states as well as two-phase regions of melting and evaporation. Results obtained on construction, calculation of the phase diagrams and thermodynamic properties of 30 simple and refractory metals are discussed. Major attention is given to the region of the phase diagram occupied by the hot dense liquid.
