Special misorientations in localized deformation regions in Fe-3% Si alloy single crystals

--Extended regions located at an angle of 20° to the rolling plane are observed inside deformation bands in a (110)[001] Fe-3%Si alloy single crystal at a high strain (~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} matrix. The misorientations between the bands and the matrix group around special misorientations ∑9, ∑19a, ∑27a, and ∑33a, which are characterized by close angles of rotation about axis . During primary recrystallization, the (110)[001] grains growing from the bands retain segments of the corresponding special boundaries with the deformed matrix. DOI: 10.1134/S1063784214080192
