Al killed steel sheet was annealed at 500?℃ through conventional annealing and electric field annealing respectively and then the sample was annealed at 750?℃ to investigate the effects of electric field on recovery and on recrystallization. The results show that the electric field affects considerably the recovery and recrystallization process,and the grain size and the intensity of recrystallization texture of the sheet. The electric field annealing retards the recover process and decreases recrystallization grain size. And it reinforces γ fiber texture and decreases α fiber texture. These can be interpreted due to a decrease in the driving force of recrystallization that would hinder the nucleation and grain growth in particulate orientations i.e. the electric field promotes the growth of grains with γ orientation and restrains the growth of grains with the other orientation. In addition,with the application of electric field during recovery,the electric field recovering is restrained the development of γ fiber texture.
