| Abstract Scope |
Scanning electron microscope (SEM) and electron backscatter diffraction (EBSD) were used to study the precipitation behavior, microstructure and texture evolution of the second phase in Y-oriented silicon steel. The results show that after the addition of rare earth Y, the inclusions are mainly spherical or ellipsoidal Y2O2S, which can effectively inhibit the precipitation of elongated MnS inclusions in the hot-rolled sheet. Rare earth treatment reduced the total number of inclusions by 14%, of which small inclusions decreased by 18% and large inclusions increased by 3.5%, but the average size of total inclusions increased by only 0.24 μm. The addition of rare earth Y reduces the unfavorable brass texture in the hot-rolled sheet, increases the number of shear bands in the cold-rolled sheet, and improves the strength of the {111}<112> texture in the decarburized sheet. After high temperature annealing, perfect secondary recrystallization occurred, and excellent magnetic properties were obtained. |
