Notes:
Effects of electric field annealing on recrystallization texture and averageplastic strain ratio (r value) of IF steel sheet were studied by mean of X ray diffractionODF analysis and the tensile test. Specimens of 75% cold-rolled IF steel sheet wereannealed at 850flC for 25min,with and without electric field annealing respectively.Results show that the electric field annealing does not change the type ofrecrystallization texture and its formation mechanism in IF deep-drawing steel sheet,but improves the formation and development of recrystallization i-fiber texture,enhances the intensity of i-fiber texture, and retards the formation and development ofc-fiber texture. Comparing with the conventional annealing, electric field annealingimproves the average plastic strain ratio (r value). Possible reasons for theintensification of recrystallization i-fiber texture with the electric field applied mayattribute to the reduction of stored energy, thus hindering the formation of otherorientated nuclei and enhancing the nucleating ratio of i-oriented nuclei. And theintensification of recrystallization i-fiber texture was considered as the main reasonfor the enhancement of the plastic strain ratio (r value) in IF steel sheet
