Abstract
It is shown that upon cold rolling the deformation of an Fe-3% Si-0.5% Cu single crystal with a (110)[001] orientation occurs, along with slip, by twinning in the (112)\([\bar 1\bar 11]\) and (11\(\bar 2\))\([\bar 1\bar 1\bar 1]\). systems. Upon a reorientation of the crystal lattice due to the operation of the slip system (112)\([\bar 1\bar 11]\), the twins of the (112)\([\bar 1\bar 11]\) type occupy a regular position in the octahedral matrix (111)\([\bar 1\bar 12]\), retaining a special misorientation Σ3 with the matrix in the entire process of deformation. The twinning system (11\(\bar 2\))\([\bar 1\bar 1\bar 1]\) occupies an irregular position in the (111)\([\bar 1\bar 12]\), matrix, but also proves to be in a special misorientation Σ3 with it. A dislocation mechanism is suggested, which makes it possible to explain the retention of the special misorientation and the inclination of the habit plane of twins of both systems of twins.
