0. 003 1N) 0. 8 mm cold-rolled sheet during annealing at 500 ~800 ℃ are studied and the forming mechanism of ｛111｝ recrystallization textures and evolution law of structure of IF steel during batch annealing process are analyzed by X-ray diffraction technique combined with microstructure observation. Results show that with increasing annealing temperature the recrystallized volume increases

the real recrystallization temperature of test steel is 640 ℃

and with increasing annealing temperature the density of {111}  recrystallized textures gradually increases

the {111} oriented grains mainly form during recrystallizing process and during growing process of the {111} oriented grains

the transfer between γ fiber textures occurs

it is mainly from {111} < 112 > texture transfers to {111} < 110 > texture.
