Abstract Sharp Goss texture in grain-oriented electrical steel needs the occurrence of fully secondary recrystallization during high temperature annealing. Given that suitable primary recrystallized microstructure is one of the key factors for abnormal Goss grain growth, it is essential to investigate the primary recrystallization microstructure evolution. Microstructures of primary recrystallization under different decarburization annealing time of low temperature thin-gauge grain-oriented silicon steel were investigated, and the influence of primary recrystallization microstructure on secondary recrystallization behavior was studied. The results show that optimum decarburization annealing time is about 3 min at 880 ℃, complete secondary recrystallization can occur during high temperature annelaing. With decarburization annealing time prolonged, the average primary recrystallized grain size increased, while secondary recrystallization is more incomplete, “fine grains” is appeared after high temperature annelaing. It could be concluded that the instability of secondary recrystallization is mainly caused by {100} 〈025〉 grains growth in the central layer, the orientation of “fine grain” without secondary recrystallization is also {100} 〈025〉 grains.

Key words： thin-gauge grain-oriented silicon steel primary recrystallized microstructure grain size “fine grains” secondary recrystallization
