Abstract

The PANDA code was used to develop an equation of state (EOS) for iron. Separate EOS tables were constructed for four solid phases and the fluid phase. The phase diagram and multiphase EOS table were then computed using the free energies. The results are in good agreement with thermophysical, static compression, phase boundary, and shock‐wave measurements. Predicted pressures for the shock‐induced e−γ and γ‐ liquid transitions agree with those determined from sound speed measurements. The predicted melting temperatures fall in between two recent sets of experimental data which sharply disagree with one another.
