| Research Abstract |
Differential thermal analysis was carried out for ferromagnetic material MnBi in the temperature range 300-773K in magnetic fields up to 45 T. The decomposition temperature Tt (MnBi -> Mn1.08 Bi + liquid) increases from 632 K (at a zero field) to 714 K by applying a magnetic field of 45 T. In addition, the Bi-Mn phase diagram at 18 T was obtained, which quite different from that at a zero magnetic field. We also obtained the Fe-C steel phase diagram under high magnetic fields over 18 T. The thermodynamic calculations of the Bi-Mn binary phase diagram in high magnetic fields are carried out by the Computer Coupling of Phase Diagrams (CALPHAD) method. The calculated results show the significant change of the Bi-Mn phase diagram under magnetic fields, which were in good agreement with the experimental results of in-field thermal analysis performed by our research group.
