Effect of rolling on the residual stresses and magnetic properties of a 0.5% Si electrical steel. Journal of Magnetism and Magnetic Materials, v. 320, p. e377-e380, 2008.0304-8853https://repositorio.fei.edu.br/handle/FEI/2272Cold-rolled (0-19% of reduction) 0.5% Si electrical steel sheets were studied in detail, including macro and micro residual stress measurements, crystallographic texture, dc-hysteresis curves and iron losses. Even for the smallest deformation, losses increase significantly, with large increase of the hysteresis losses, whereas the anomalous losses reduce slightly. The residual microstresses are ∼150-350 MPa, whereas residual macrostresses are compressive, ∼50 MPa. The large increase of the hysteresis losses is attributed to the residual microstresses. The dislocation density estimated by X-ray diffraction is in reasonable agreement with that predicted from the Sablik et al. model for effect of plastic deformation on hysteresis. The intensity of the texture fibers {1 1 1} 〈u v w〉 and 〈1 1 0〉//RD (RD=rolling direction) increases with the reduction. © 2008 Elsevier B.V.
