The formation and control of sharp{100} 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}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}texture in fairly thick sheets is obtained. After primary recrystallization,a weak component of{100}and strong component of (447)texture,which constitute ∑9 coincidence site lattice boundaries with a common axis for 39°difference,are presented.This special grain boundary promotes the growth of{100}grains in addition to the lower surface energy of(100)grains during secondary recrystallization.
