Thermodynamic assessment of the Ce–Mn system

The binary Ce–Mn system is investigated via key experiments and thermodynamic modeling. The phase diagram data available in the literature are critically reviewed. Four key alloys are prepared by arc melting the pure elements, annealed at 600 °C for 8 days and then subjected to X-ray diffraction (XRD) analysis for phase identification and to differential thermal analysis (DTA) for measurement of phase transition temperatures. The thermodynamic optimization of the Ce–Mn system is performed by considering the experimental data from the literature and the present work. A consistent thermodynamic data set for the Ce–Mn system is obtained by optimization of the selected experimental data. The calculated phase diagram agrees well with the experimental data.
