摘要
The formation and control of sharp {100}〈021〉 texture in electrical steels were experimentally investigated and the main influencing factors were discussed. The steels of a base composition of Fe-3.2%Si with a certain amount of carbon and manganese were employed to obtain {100}〈021〉 texture through one stage cold rolling and annealing. The results indicated that by careful control of the amount of alloying elements and the annealing temperature, a relatively sharp {100}〈021〉 texture in fairly thick sheets is obtained. After primary recrystallization, a weak component of {100}〈021〉 and strong component of （447） 〈18114〉 texture, which constitute ∑9 coincidence site lattice boundaries with a common 〈011〉 axis for 39° difference, are presented. This special grain boundary promotes the growth of {100}〈021〉 grains in addition to the lower surface energy of （100） grains during secondary recrystallization.
