Abstract
Most of the electrical steel slabs are composed of {100} columnar grains. After hot rolling, there is a texture gradient across the thickness. The surface shear textures (Goss texture{110} , Brass texture{110} , Copper texture{112} ) and certain //ND fiber textures after hot rolling can be inherited into the finished sheet. The volume fraction and distribution of these textures after cold rolling significantly influence the magnetic properties. Therefore, a full-field crystal plasticity finite element method (CPFEM) was employed to simulate the evolution of microstructure and orientations of {100} columnar grains under plane strain compression and an additional displacement gradient component L13. Through qualitative and quantitative analysis of the simulated microstructure, it was found that under plane strain compression, {100} grains were the most stable, followed by {100} grains. Nearly {100} orientation rotated towards {114} orientation at the extremities of the simulation block. The additional displacement gradient component L13 enhanced the rotational effect. At the 45° shear direction and ends of the simulation block, the {110} orientation originated from {100} grains, the nearly {110} orientation formed from {100} grains, and the {112} Copper orientation derived from {100} grains. However, the simulation did not demonstrate the development of Goss shear orientation.
