摘要: 借助于光学显微镜研究了强磁场(12 T)下奥氏体化温度对Fe-0.12%C合金连续冷却转变显微组织形貌的影响, 结果表明: 随着奥氏体化温度的升高, 铁素体晶粒沿磁场方向伸长且呈链状排列, 珠光体团长轴方向与磁场方向平行且伸长的程度增强; 相同强磁场热处理条件下, 板平面平行于磁场方向比垂直于磁场方向放置的试样的铁素体面积百分含量高, 同时铁素体晶粒沿磁场方向伸长且呈链状排列, 珠光体团长轴方向与磁场方向平行且伸长的程度低.

Abstract：The influence of austenization temperature on the morphology of pearlite in Fe-0.12%C alloy under high magnetic field (12T) was investigated by using optical microscopy. It is shown that the tendency that the long axis of the pearlite grains is parallel and elongated along the magnetic field direction under the high magnetic field becomes stronger as the austenization temperature increases. This is due to the fact that austenite grain in the sample austenized at higher temperature is larger and thus the distance between the nuclei of the proeutectoid ferrite at the triple grain boundaries is larger, leading to a stronger chain alignment of the ferrite grains along the magnetic field direction. As a result of the difference of demagnetization field arising from different disposal conditions of the plate samples, in the samples austenized at the same temperature and under the same magnetic field strength the percentage of the pearlite in the sample whose plate plane is parallel to the magnetic field direction is lower than that in the sample whose plate plane is perpendicular to the magnetic field direction, and the tendency that the long axis of the pearlite grains is elongated along the magnetic field direction in the sample whose plate plane is parallel to the magnetic field direction is weaker than that in the sample whose plate plane is perpendicular to the magnetic field direction 。

Key words： high magnetic field diffusional solid state phase transformation Fe-C alloy pearlite demagnetization
