| Abstract | The structural dependence of crystal-melt interfacial free energies (γ) is investigated for fcc and bcc solids through molecular-dynamics calculations employing interatomic potentials for Fe. We compute ≈30-35% lower values of γ for the bcc structure, and find that our results cannot be explained simply in terms of differences in latent heats (L) or densities (ρ) for bulk bcc and fcc phases. We observe a strong structural dependence of the Turnbull coefficient α = γ/Lρ2/3, and find a trend towards lower crystalline anisotropies of γ for the bcc structure relative to fcc. © 2004 The American Physical Society. |
