the effect of cold rolling process on the microstructure and texture evolution in a 1 wt. % si non-oriented electrical steel

In this study, the effect of cold rolling process on the microstructure and texture evolution in 1wt. % si non-oriented electrical steel was investigated. for this purpose, all samples were processed through single-stage hot rolling at 1100 ° c and two-stage cold rolling (cross rolling and unidirectional rolling) with intermediate annealing at 650 °c for 35 seconds. finally, all of them were fully annealed for 3 min at 900 ° c. the results showed that cold rolling process could affect shear band formation, deformation texture and annealing texture. shear band and {322} grains were decreased and {100} grains were increased by the cross rolling method. these observations showed the weakening of the {110} <001> and {111} <112> components and the strengthening of the {001} <110> component after final annealing for the cross rolled sample. on the other hand, shear band formation in the unidirectional rolling sample caused the development of annealing goss texture component ({110} <001>).
