To find out the reason of poor secondary recrystallization behavior in thin-gauged grain-oriented steel, EBSD technique is applied to reveal the grain growth behavior of thin-gauged steel processed by HiB steel method under high cold-rolling reduction. Nitriding treatment with different times is conducted to ensure the occurrence of secondary recrystallization in thin-gauged grain-oriented steel and to determine the effect of nitrogen content. Attention is put on the influence of 114 418 texture on the abnormal growth of Brass and Goss grains. Results show that, at initial stage of secondary recrystallization, 114 418 grains in the surface region of sheets possess obvious growth advantage than the other oriented grains. If these grains in the surface region grew to the central layer of sheet and swallowed the nucleus of secondary recrystallization, abnormal growth could not occur. In contrast, reinforcing the inhibitors at surface region of sheet by nitriding treatment will avoid the excessive growth of surface grains and therefore improve magnetic properties of steel significantly. The {114}<418> grains are adverse to the abnormal growth of Brass-oriented and scattered Goss grains in way of island grains, but their effect on the abnormal growth of Goss grains is weaker.
