First Principles Calculations on Iron and Iron alloys

Equation of state of hcp- and bcc-Fe and FeSi, the bcc-hcp phase transition, the magnetic moment of bcc-Fe, the elastic constants of bcc-Fe, the bcc-bct distortive phase transition and the phonon frequencies for bcc- and fcc-Fe [6];
hcp-Fe is the likely phase for a pure iron core on thermodynamic grounds [8, 14, 29];
Although bcc-Fe is mechanically destabilised by pressure, temperature may enable it to become mechanically stable at core conditions (stress tensors and position correlation functions) [34, 60]
Although thermodynamically less stable than hcp, bcc-Fe could be stabilised by light elements such as Si [27, 31];
