Orientation rotation at grain boundary regions in Fe-3.0 wt.% Si non-oriented silicon steel is investigated using crystal plastic simulation. The study reveals that the rotation tendency and rotation velocity field at grain boundary regions are significantly influenced by neighboring orientations. Control over deformation texture at grain boundary regions can be achieved by designing the initial texture based on the rotation influenced by neighboring orientations.
Orientation rotation at grain boundary regions associated with neighboring orientations in Fe-3.0 wt.% Si non-oriented silicon steel has been investigated by crystal plastic simulation. Rotation tendency relative to a certain target orientation is evaluated by deviation angle variation. Taking ideal lambda (< 001 >//ND, normal direction) as the target orientation, the deviation angle of scattered {001} < uv0 > orientations at grain boundary regions affected by neighboring orientations during rolling is calculated and verified by experimental measurements. The rotation tendency and rotation velocity field at grain boundary regions are significantly changed by neighboring orientations. According to the neighbor affected orientation rotation, the initial texture can be precisely designed to control the deformation texture at grain boundary regions.
