The Improvement of Primary Texture for Sharp Goss Orientation on Grain Oriented Silicon Steel

抄録

The relationship between primary and secondary recrystallization texture, and the improvement of primary texture on grain oriented silicon steel was examined. The specimens were prepared by using different C content and different hot rolling conditions in the acquired inhibitor method. Higher reduction of the later passes of hot rolling gave the same effect to primary texture as more C content. As a result, the sharpness of Goss texture became similar. Higher reduction of the last two passes of hot rolling caused {411}‹148› texture to enhance, and higher C content caused {111}‹112› texture to enhance in primary texture. Both orientations are ∑9 orientations of Goss. As a result I_C∑9 of Goss is enhanced. Furthermore, not only ∑9 orientations but also ∑5 might contribute the secondary recrystallization.
