摘要：
The grain size distributions of {411} <148>, {111} <112> and {100} <025> in primary recrystallized and secondary recrystallized specimens in TG-CRGO steel were investigated by EBSD technique, and the effects of these three kinds of primary recrystallized grains on abnormal growth of Goss grains were analyzed. The results show that in primary recrystallized specimens, the average grain size order from large to small is {411}<148>, {100} <025> and {111} <112> grains. The abnormal growth process of the Goss grains could be extracted as follows: the {111}<112> grains are preferentially swallowed, then the {411} <148> grains, and finally near the {100} <025> grains and near the Brass grains. {411} <148> and {111} <112>grains would hinder the abnormal growth of Goss grains at preliminary stage. Therefore, it could be assumed that the residual island grains after final annealing mainly came from near {110} <112 >grains or near {100} grains. © 2018, Materials Review Magazine.
