N2 - AA 5005, 5052, 5754 and 5182 continuous cast aluminum alloys, which were all fully recrystallized, were cold rolled at different reductions. X-ray diffraction was used to measure pole figures of these rolled samples, and the corresponding ODFs were calculated. A modified integration method was used to quantify the volume fractions of all the texture components in these samples by integration of the intensity function over the subdivided Euler space for each texture orientation instead of over an arbitrarily defined region around the orientation. The subdivision of Euler space was made according to the slip characteristics of each ideal texture orientation. It was found that a general Avrami relationship exists between the texture volume fraction and the true strain of the cold-roll deformation. The calculated volume fractions of cube, r-cube, Goss, r-Goss, β-fiber and remainder orientations were consistent with those experimentally measured in all the Al alloys studied in this work. Such an Avrami type relationship can also be determined to reflect the effect of alloying elements on texture development in these alloys.
