Lattice reorientation in the shear bands of $\{112\}$ $\langle$131$\rangle$ crystallites in an Fe-3%Si alloy

Subregions (0.1 $\mu$m) with the $\{110\}$ $\langle$113$\rangle$ orientation form in shear bands in grains with the $\{112\}$ $\langle$131$\rangle$ orientation in a deformed ($\varepsilon\approx$ 50%) polycrystalline Fe-3%Si alloy sample. The relationship between the matrix and the subregions in the shear bands is described by a special misorientation close to $\Sigma5$. It is assumed that the subregions that have a $\{110\}$ $\langle hhl\rangle$ orientation and special misorientation $\Sigma5$ with the surrounding matrix and form in the shear bands of crystallites with orientations other than $\{111\}$ $\langle$112$\rangle$ can serve as anomalous growth nuclei during heat treatment because of a high density of special $\Sigma5$ boundaries.
