Secondary recrystallization behavior in the presence of AlN and MnS precipitates in Fe-3% Si alloy, processed by one stage cold rolling method, was investigated with special reference to a role of inhibitor for secondary recrystallization. The sharpness of Goss secondary texture is higher in the early stage of secondary recrystallization. In the case of stronger grain growth inhibition by precipitates during secondary recrystallization, the evolution of secondary recrystallized grains in orientations dispersed from Goss orientation is smaller than that in the case of weaker grain growth inhibition. The mechanism of these experimental results is explained by the specific grain boundary migration characteristics in the presence of inhibitor, namely, the critical frequency of [Sigma]9 coincidence oriented grains in relation to nucleus for the evolution of secondary recrystallization is considered to be higher in the case of stronger grain growth inhibition during secondary recrystallization.
