Formation and Control of Sharp {100}＜021＞ Texture in Electrical Steel

Keywords： {100}<021>texture

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)<18 11 4>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.
