Résumé

To illustrate how the texture evolution of a polycrystalline aluminum alloy is dependent on the deformation path, hot extruded AA6082 plates in T6 conditions were rolled with various deformation modes. Unidirectional and cross-rolling were conducted at room temperature for different levels of thickness reduction. The resulting textures were then evaluated using the electron backscatter diffraction technique. Depending on the extent of deformation, different textures were obtained. The strong texture of the initial hot extruded material influences texture development and provides new insights into texture development in aluminum alloys. The evolution of the Cube component was particularly interesting in this matter. A competition between dislocation glide and crystal rotation could explain the observed results. The comprehension of these mechanisms leads to a better understanding of texture evolution that drives many properties in aluminum alloys.
