The Possibility of Obtaining Electrical Steel with Texture {100} <001>

Abstract:

We have investigated the cold rolling mesostructure and recrystallization of BCC crystals {110} <110> Fe-3%Si using a method of orientation microscopy. The 40% deformation caused shear bands with habit plane at a slope of ~20 ... 28° to the direction of rolling to form a "fishbone"-type structure. The orientation of the crystal lattice in SBs was close to {100} <001>. It can be represented as a rotation around TD close to the crystallographic direction [001] at an angle of ~ ± 37°. Such disorientation corresponds to the special disorientation CSL Σ5 (36.87о, axis [001]) between SBs and the matrix. Primary recrystallization centers in previously deformed crystal {110} <110> are formed primarily in SBs. Their orientation appears to be close to the orientation {100} <001>. It has been shown that the usage of patterns of texture formation in the shear bands of original crystallites {110} <110> allows to obtain electrical steel with a cubic texture {100} <001>.
