【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。
【Abstract】 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 decarbu…
