Extensive neutron texture analysis of extruded Al–Cu composites was conducted in order to investigate the influence of material composition as well as various processing conditions (extrusion temperature, heat treatment) on the texture development in both phases. Texture changes in cold extruded and subsequently heat treated samples were investigated up to 400℃. Moreover, the texture of a series of cold extruded samples was compared with that of warm extruded samples. It was found that the recrystallization behaviour of the two metals differs and that the stacking fault energy has a large influence on the recrystallization texture.
