Abstract:
A semi-empirical equation of state for iron with allowance for five condensed phases (($\alpha$, $\gamma$, $\delta$, $\varepsilon$, and liquid phases), evaporation, and thermal ionization is derived. As a whole, results of model calculations are consistent with static and dynamic experimental data in the pressure range from the atmospheric value to $\approx$ 10 TPa and in the temperature range from room temperature to $\approx$ 10$^5$ K. The viscosity of liquid iron under conditions typical for the Earth core is estimated on the basis of the liquid model.
Keywords:
iron, equation of state, phase diagram, melting, evaporation, shock adiabat, isotherm, velocity of sound, viscosity.
