To examine magnetic field effects on the BiMn equilibrium phase, a high-magnetic fields differential thermal analysis (HF-DTA) was performed for fields up to 18T and temperatures ranging from 300 to 753K. For zero field, the peritectic temperatures Tp1 (BiMn1.08 + Bi-rich liquid1⁄4 BiMn) and Tp2 (iMn + Bi-rich liquid1⁄4 BiMn1.08), and the eutectic temperature TE (the Bi-rich liquid 1⁄4 Bi solid + BiMn) were determined to be 632, 721 and 538K, respectively. The BiMn phase diagram at 18T was obtained, which showed that Tp1 increases with increasing magnetic fields at the rate of 2KT11. Furthermore, the liquidus boundary temperature Tliq between BiMn1.08 + liquid and Bi-rich liquid was found to increase nonlinearly with increasing magnetic field. [doi:10.2320/matertrans.M2012310]
