Abstract OM, SE, EDS, EBSD and other techniques were used to observe and analyze the structure and orientation of the secondary recrystallization interrupted extraction samples. The results show that when the holding time of high temperature annealing reached 5h, some grains had secondary recrystallization. With the extension of thetime of secondary recrystallization, the number of secondary recrystallization grains significantly increased. Goss texture increased with the extended of holding time, while the texture contents of {111}〈112〉 and {411}〈148〉 significantly decreased. The Goss texture content reached 91.1% and its strength reached 284.771 at the time of annealing for 25 h. The inhibitor gradually coarsens with the extension of the high-temperature annealing time, and its pinning of the grain boundary gradually weakens until the inhibitory effect is completely lost.
