Texture evolution during indirect extrusion of cylindrical profiles of an AlSiMgMn aluminium alloy was investigated in the present work. The effect of extrusion temperature on texture development, through-thickness texture variations and texture variations along the length of the extruded profiles were investigated. In all cases a combined 〈100〉 and 〈111〉 fibre texture developed. Generally, the 〈111〉 fibre was sharper than the 〈100〉 fibre. The texture evolution was rather similar along the length of the profile, while the variations through the thickness were considerable. In a region midways between the centre and the surface of the profiles, the 〈100〉 fibre was weakened, and in the surface regions the two fibres were significantly rotated. The texture measurements showed a strong dependence on extrusion temperature, in the sense that the higher the temperature, the sharper the 〈100〉 fibre texture. The influence of texture variations on formability were also investigated.

The in situ experimentation technique in HVEM seems to be particularly suitable to clarify the processes involved in recrystallization. The material under investigation was unidirectionally cold-rolled titanium of commercial purity. The problem was approached in two different ways. The three-dimensional analysis of textures was used to describe the texture evolution during the primary recrystallization. Observations of bulk-annealed specimens or thin foils annealed in the microscope were also made in order to provide information concerning the mechanisms involved in the formation of new grains. In contrast to the already published work on titanium, this investigation takes into consideration different values of the cold-work ratio, the temperature and the annealing time.Two different models are commonly used to explain the recrystallization textures i.e. the selective grain growth model (Beck) or the oriented nucleation model (Burgers). The three-dimensional analysis of both the rolling and recrystallization textures was performed to identify the mechanismsl involved in the recrystallization of titanium.
