STUDY OF COLD ROLLING DIRECTION ON DEVELOPMENT OF CUBIC TEXTURE IN GOSS Fe_Si SOFT MAGNETIC LAMINATIONS

The development of cubic texture (100)[0kl], after double stage cold rolling and heat treatment, has been studied in soft magnetic Fe-3 wt % silicon laminations with initial (110)[001] texture. Original laminations with Goss texture have been heat treated after a single stage cold roll following their initial direction of rolling to develop primary nuclei of cubic grains. The effect of a second cold roll following initial or traverse directions has been studied after the final heat treatment of the sheets. Following the results, strong cubic textures with less second stage cold rolling have been obtained in a traverse direction. Cubic textures in thicker sections were a result of traverse second stage cold rolling.
