Abstract

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 18 T and temperatures ranging from 300 to 753 K. For zero field, the peritectic temperatures Tp1 (BiMn1.08 + Bi-rich liquid → BiMn) and Tp2 (αMn + Bi-rich liquid → BiMn 1.08), and the eutectic temperature TE (the Bi-rich liquid → Bi solid + BiMn) were determined to be 632, 721 and 538 K, respectively. The BiMn phase diagram at 18 T was obtained, which showed that Tp1 increases with increasing magnetic fields at the rate of 2KT-1. Furthermore, the liquidus boundary temperature Tliq between BiMn1.08 + liquid and Bi-rich liquid was found to increase nonlinearly with increasing magnetic field.
