Abstract: The twin-roll cast Fe-2.8%Si-0.8%Al strips were directly cold rolled and annealed to investigate the effect of cold rolling reduction on deformation and recrystallization texture. The deformation texture is mainly composed of α, γ and λ fibers with peak at 001<110>, 111<110> and 001<110>~<210>, respectively. The main deformation texture components are enhanced when the reduction increases from 40% to 90%, while the shear banding becomes the most notable feature at 60% reduction. The recrystallization texture is characterized by Goss, λ fiber, 113<361>, Cube and 111<112> components. The dominant nucleation sites transform from shear bands to deformation bands and grain boundary regions as the cold rolling reduction increases, resulting in the weakening of Goss and the strengthening of λ fiber, 113<361>, Cube and 111<112> components.

Key words: cold rolling reduction, non-oriented silicon steel, twin-roll strip casting, deformation texture, recrystallization texture
