    Abstract

    During final annealing, microalloyed sulfur in thin-gauged silicon steel segregates to the strip surface and on grain boundaries and thus affects the texture development. With increasing flow rate of hydrogen, the profile of magnetic induction was shifted to a shorter annealing time, and the time range of lower magnetic induction was drastically shortened. This is ascribed to the faster depletion of surface-segregated sulfur that accelerates surface-energy-induced selective growth of (110)[001] Goss grains. After final annealing for 14.4 ks, the strips showed a high magnetic induction of about 1.9 T. By controlling the surface segregation behavior of sulfur, it is possible to achieve the surface-energy-induced selective growth of grains favorable for magnetic induction in thin-gauged silicon steel.
