Descrição: dc.descriptionThe effect of thermomechanical processing on the formation of shear bands and on the magnetic properties of a3.0wt% silicon non-oriented steel was investigated by hotrolling samples with different thick nessesat different temperatures, in order to obtain a variation in hot band grain size and cold strain. All the samples were processed in a single-stage cold rolling and finally annealed at 1020 1C. It was found that thein crease of the hot band grain size decreases the g fiber volume fraction and increases the Z fiber volume fraction after the final annealing. The increase of the cold strain strongly contributed to this result. A good combination of intense generation of shear bands, and proper crystallographic texture, due to higher nucleation of grains with favorable orientations to magnetiza-tion in these bands, can be obtained for the samples hot rolled at 1000 and 1120 1C and submitted to cold strain of 64.3% and 72.2% respectively. However the best combination of B50, W15/60 and mr can be obtained by hot rolling the samples at 1000 1C to the thickness of 1.4mm, corresponding to 64.3% of cold strain.-
