摘　　要：采用自主研发的脉冲磁场退火装置,在取向硅钢脱碳退火过程中分别施加不同强度的磁场,并采用光学显微镜和X射线衍射仪研究了脉冲磁场脱碳退火后试样的显微组织和宏观织构。结果表明,脱碳退火过程中施加脉冲磁场后取向硅钢的平均晶粒尺寸均增加,当磁场强度为40 mT时,平均晶粒尺寸最大,为13.06μm。此外,取向硅钢试样的立方织构{001}<100>强度减弱,高斯织构{110}<001>和{111}<112>织构增强,有利于获得更好的成品织构和磁性能。Self-developed pulsed magnetic field annealing device was used to apply magnetic field of different intensities during decarburization annealing of an oriented silicon steel, and microstructure and macro-texture of the specimens after decarburization annealing in a pulsed magnetic field were studied by using optical microscope and X-ray diffractometer. The results show that the average grain size of the oriented silicon steel increases with the application of pulsed magnetic field during decarburization annealing. The maximum average grain size is 13.06 μm when the magnetic field intensity is 40 mT. In addition, the strength of cube texture {001}<100> of the oriented silicon steel specimen is weakened, while the Goss texture {110}<001> and {111}<112> are strengthened, which is conducive to obtain better texture and magnetic properties of the finished product.
