Abstract The microstructures and textures during recrystallization process in the aluminium sheet which had been longitudinally and transversely rolled were investigated. The oriented growth during the recrystallization was directly observed by transmission electron microscope and the orientation relationships of new grains were determined by electron diffraction. The pole figures were measured with X-ray diffraction goniometer and ODF's were calculated by Bunge's method. The results showed that recrystallized grains with some oriented relationship to the deformation matrix grew more rapidly than others, which leads to the final texture. In fcc metal, this orientation relationship is about 40° <111>.
