High-pressure Melting Curves of α and ¥ Phases of Iron

Statistical moment method (SMM) has been applied in combination with Lindemann melting criterion to investigate pressure effects on melting temperature of iron. Melting curves of phase with body-centered cubic structure and phase with face-centered cubic structure of iron have been derived up to p...
