Abstract

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 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.

Key words: oriented silicon steel, microstructure, texture, magnetic induction intensity
