Abstract High voltage electronic aluminum foil, prepared by segregation method, was studied about its the recrystallization behaviour during the annealing process using electron back-scattered diffraction (EBSD) and X-ray diffraction (XRD). And cellular automaton (CA) model was established to make a further analysis on the different recrystallization phenomena from the perspective of energy. The experimental results of stepping-annealing show that the grains of the S orientation ({123}〈634〉) and the Cu orientation ({112}〈111〉) obtained advantage in growth through in-situ recrystallization in the low-temperature annealing, which grew rapidly and formed R_S and R_Cu recrystallization texture at the later high temperature period, but the nucleation of cube ({001}〈100〉) grains were inhibited. Then annealing at a higher temperature, cube grains tended to nucleate and grow preferentially, which led to the formation of strong cube texture. Seen from the results of cellular automaton model, distinction of textures mainly depends on the energy difference between these two annealing conditions.
