Abstract
Considerable discrepancy was observed in the measured activity (chemical potential) of Nd reported in the literatures on molten Nd‒Fe system. The activity of Nd in molten Nd‒Fe(‒B) alloys was measured by the electromotive force (EMF) method using a specially-fabricated Nd concentration cell. The activity of Dy in molten Dy‒Fe(‒B) alloys was also investigated for verification. The measured activity of Nd in the molten Nd‒Fe(‒B) alloys was close to that observed in the ideal solution, which was in accordance with the data reported by Hennemann et al. The presence of B in the molten alloys did not significantly influence the activity of Nd in the studied concentration range. The measured activity of Dy in Dy‒Fe(‒B) alloys was similar to that observed in the ideal solution. The results obtained were consistent with the latest phase diagram studies, including the assessments that applied the Calphad technique.
