Abstract: The effect of the inter-annealing temperature and heating rate of final annealing on the microstructure of high-vol-tage anode aluminum foils was investigated by electron back scattered diffraction (EBSD) and X-ray diffraction (XRD). The results demonstrated that the inter-annealing temperature played a key role on the formation of cube texture in the final products, because the low inter-annealing retained lots of deformation stored energy and provided great driving force for the nucleation. Simultaneously, the cube texture deflected dramatically from the idea position at a lower inter-annealing temperature. With the increase of annealing heating rate during final annealing, the fraction and grain size of recrystallization decreased gradually, because a higher annealing heating rate (below the critical heating rate) reduced the time available for grain boundary migration and retarded the recrystallization.
