Abstract:
The previously developed wide-range multiphase equation of state of Fe was used to calculate the shock pressure causing its evaporation during isentropic unloading up to 10−4 GPa (1 atm). Calculations were made for three initial states of matter: pressure 1 atm and temperature 298 K (“cold” initial state), 1 GPa and 1500K (“warm” state), and 40 GPa and 4000 K (“hot” state). The shock pressure is 359, 261, and 132 GPa, respectively. These values are generally lower than the estimates of other authors. Arguments are given in their justification.
