Abstract: Extended regions located at an angle of 20$^\circ$ to the rolling plane are observed inside deformation bands in a (110)[001] Fe-3%Si alloy single crystal at a high strain ($\sim$60%). These regions were interpreted earlier as shear bands. The lattice orientation in these bands is close to (110)[001], and their habit plane is parallel to the $\{112\}$ planes of the deformed $\{111\}$ $\langle$112$\rangle$ matrix. The misorientations between the bands and the matrix group around special misorientations $\Sigma9$, $\Sigma19a$, $\Sigma27a$, and $\Sigma33a$, which are characterized by close angles of rotation about axis $\langle$110$\rangle$. During primary recrystallization, the (110)[001] grains growing from the bands retain segments of the corresponding special boundaries with the deformed matrix.
