采用热电偶直接测量和定量金相分析方法，研究了11.5T磁场对Mn-Sb系合金凝固过程相平衡的影响。结果表明，磁场可增加共晶线和MnSb的面积分数，从而使共晶点向高Mn浓度侧移动。随着Sb含量的增加，Sb的液相线温度呈下降趋势，但对MnSb的液相线温度影响不大。上述结果可能与相变过程中磁化率的变化有关。
The effects of an 11.5T magnetic field on phase equilibria of Mn–Sb system during solidification process were investigated with the aid of direct thermocouple measurements and quantitative metallography analysis. It was found that the magnetic field could increase the eutectic line and the area fraction of the MnSb in eutectics, and thus shift the eutectic point to the high Mn concentration side. It could also increase the Sb liquidus temperatures by a decreasing trend with an increasing Sb composition, but show little effect on the MnSb liquidus temperature. The above results could be related to the variation in the magnetic susceptibility during the phase transformation.
