Development of texture and microstructure of commercial high permeability silicon steel during rolling and recrystallization were studied by Orientation Distribution Functions (ODFs) and optical and electron microscopy. The present results confirm former single crystal results that large {111}<112>-oriented cold rolled grains containing shear bands are the origin of the Goss texture after primary and secondary recrystallization. The formation of {111}<112>-oriented grains during intermediate cold-rolling can be explained by relaxed constraint models. In the case of iron-silicon their orientation density is still enhanced by the transformation of the shear texture in the hot band subsurface during cold rolling. Formation of Goss nuclei in shear bands together with growth preference of the Goss nuclei in these grains leads to a primary recrystallization texture containing Goss grains.
