Abstract: The microstructures and textures in the cold rolled aluminium strip at different strains have been investigated. The rolling reductions of interest were from 25%( ε =0.28)to 92.5%(ε=2.59). The mechanical properties of the strip at different angles to rolling direction were measured by uniaxial tensile testing. The pole figures were determined with D-500 X ray diffraction goniometer and ODF's were calculated by Bunge's method. The microstructures were studied by TEM. It was shown that the textures developed in the strip were different from those developed in the plate. The development of the microstructures, textures and mechanical anisotropy in the strip was analyzed. The influence of microstructures and textures on the plastic anisotropy was discussed.
