脉冲磁场退火对取向硅钢组织及织构的影响
|
摘要
为研究脉冲磁场对普通取向硅钢组织及织构的影响,在相同时间下对取向硅钢进行普通退火及脉冲磁场为14.1、20.6 mT下退火。用电子背散射衍射装置(EBSD)观察取向硅钢磁场退火阶段的织构、取向差及重合位置点阵(CSL)的变化。结果表明:经脉冲磁场退火后,提高λ织构的面积分数和晶粒尺寸,促进二次再结晶的{012}<001>织构增强,{112}<110>不利织构减弱;Σ3和Σ9晶界比增加,取向差为20°～45°的特殊晶界比也增加。
In order to study the effect of pulsed magnetic field on microstructure and texture of oriented silicon steel,the oriented silicon steel was annealed normally and annealed under pulsed magnetic field of 14.1mT,20.6 mT for the same annealing time.The texture,misorientation and coincidence position lattice(CSL)of the magnetic field annealed silicon steel were observed by EBSD.Results show that the area fraction and grain size of the λ texture are increased,the favorable textures such as {012}<001> which promote secondary recrystallization are enhanced while the unfavorable textures such as {112}<110> are weakened after pulsed magnetic annealing.The proportions of Σ9 coincidence boundaries and Σ3 coincidence boundaries are increased.The proportion of special grain boundaries with misorientation angle ranging from 20° to 45° is increased.
