Silicon iron ribbons with silicon concentration lower than 4 wt% were prepared by a rapid quenching roll method, and the size of ribbons obtained were 2 ∽4 mm in width and 40∽60 μm in thickness. The grains grew to about 2 mm and the ribbons had (100)[0kl] cube-on-face grain textures after annealing the ribbons in vacuum atmosphere. The coercive force of the 2. 5Si. 97. 5Fe ribbon was decreased to 60 mOe by annealing at 1160°C for 2 hours at the pressure of 6x10-3 Torr.
