Abstract: The development of cube texture ({001}〈100〉) in high purity (99.99%) aluminum foils in multistage annealing was investigated by ODF and EBSD. It is found that a multistage annealing process can strengthen cube texture markedly, and that each stage of the multistage annealing plays an important eigen role in nucleation and growth of the cube orientation grains. The cube orientation grain nucleates preferably at 180℃ because of its low activation energy of nucleation, the cube nuclei grow favorably at 400℃ because of the anisotropy of 40°〈111〉 growth. and the cube texture is further strengthened at 550℃ and becomes prodominent because of favorable bigger grain sizes.
