WebOct 10, 2013 · The simulation box for the pure hcp-Fe was the same as used previously (9) to determine the elastic constants of pure hcp-Fe iron. This consisted of a 4x2x2 supercell of the 4-atom C-centred crystallographic cell of the hcp structure with orthogonal axes. A k-points grid of 4 irreducible k-points was used. WebJun 11, 2012 · Comparison of our hcp-Fe and Fe-Si alloy results with previous studies on Fe at high pressures showed that hcp-Fe 0.85 Si 0.15 systematically exhibits much higher VP and much lower ρ than hcp-Fe ( 10, 31 – 34) ( Fig. 2 ). The overall alloying effects of Si in Fe have resulted in reduced density and increased velocity at high pressures.
