Abstract :
In this article, the 40 or 100/spl mu/m thick 3% Si-Fe strips with final cold rolling reduction of 30% that contain 90ppm sulphur were heated up to 1200/spl deg/C with various heating rates, prior to isothermal annealing at 1200/spl deg/C under a flowing hydrogen atmosphere. A prominent difference in final texture and magnetic induction was observed after final annealing, depending on heating rates and strip thickness.
