Abstract The present work attempts to investigate the effect of magnetic annealing on texture and microstructure of grain non-oriented (GNO) cold rolled Fe-0.75%Si steel samples. The cold rolled specimens were annealed at constant magnitude of magnetic field, 17T, for different annealing times and at different magnitudes of magnetic field at a constant annealing time, 10 minutes. In order to evaluate the effect of the magnetic field, the cold rolled specimens were also annealed at the same conditions (temperature, time and inert atmosphere) as for the magnetic annealing but without any magnetic field. EBSD/OIM, X-ray measurements and optical micrograph have being used to characterize the texture and microstructure of the samples after each annealing treatment. Magnetic annealing at high magnetic fields has shown to influence the final texture of the samples through changes in the ç, ã and á fibers. Magnetic field has not had a significant effect on the volume fraction of Goss-oriented grains but has affected the GBCD of these grains. High magnetic have shown to be a key factor for the improvement of texture and microstructure of Fe-0.75%Si steel.
