Abstract
The shear deformation texture of bcc metals is characterized by the Goss orientation, or {110}〈001〉, which is a highly useful orientation for grain-oriented silicon steels because it gives rise to high magnetic permeability along the 〈100〉 direction. To obtain the Goss texture, or {110}〈001〉, in silicon steel sheets, a silicon steel sheet was subjected to an 89 pct reduction in thickness via asymmetric rolling at 750 °C. This step resulted in the well-developed Goss texture. When multiple asymmetrically rolled steel sheets were subsequently annealed, one at 900 °C for 1 hour and the other at 1200 °C for a short period of 5 minutes in a box furnace with air atmosphere, a strong Goss texture was developed in the silicon steel sheets. The texture was measured via X-ray diffraction and electron backscatter diffraction. The magnetization curve of each specimen was measured by the vibrating sample magnetometer and the measured magnetization curve showed the typical soft magnetic characteristics.
