Phase Diagram of Fe Rich Side of Fe-Mo System under High Pressure

Abstract

High-pressure phase diagrams of the iron-rich Fe-Mo system were determined by a diffusion-couple method and the results were compared with the calculated phase diagrams. Under high pressure the α-phase region became narrower, while the γ-region wider. When the pressure was about 3.2 GPa, the γ-loop was no more present and instead the contracted γ-field appeared in the Fe-Mo system.
