研究了强磁场(12T)下冷却速度对Fe-0.12%C合金中的珠光体组织形貌的影响.结果表明:强磁场下珠光体团的长轴方向与磁场方向平行且伸长的程度随其冷却速度的提高而减弱.板平面平行于磁场方向比垂直于磁场方向放置的试样的珠光体面积分数低,同时珠光体团长轴方向与磁场方向平行且伸长的程度也低.最后,探讨了强磁场下珠光体组织形貌的演变机理.
The effect of cooling rate under high magnetic field (12T) on the morphology of pearlite in Fe-0.12% C alloy was investigated. The results show that the long axis direction of pearlite group in the strong magnetic field is parallel to the direction of the magnetic field Its cooling rate increased and weakened.Plate plane parallel to the direction of the magnetic field perpendicular to the direction of the magnetic field than the sample placed pearlite area fraction of the same time the long axis of the pearlite and magnetic field direction parallel to the extent and elongation is low. The mechanism of pearlite structure evolution under high magnetic field was discussed.
