Abstract Scope In order to explore the effect of deformation on structure and texture of 3% Si oriented silicon steel with and without Y, three different cold rolling reduction rates were carried out by using EBSD and image analysis software. The experimental results show that the density of internal shear bands gradually increases with the increase of cold rolling deformation. When the cold rolling reduction rate reaches 86%, there are lower density and strength shear bands. The grain size of cold rolled sheet containing rare earth Y was long. There are higher density and strength shear bands. The texture intensity of the cold rolled sheet is proportional to the reduction rate. However, the strength of textures decreases with increasing the reduction rate above 80%. Y greatly weakens the intensity of main texture.The γ texture strength is 7.3 in cold rolled sheet containing Y, which is significantly higher than that without Y.
