As to the effect of dispersed particles on the deformation texture, the structural analysis was carried out on the hot-extruded and cold-rolled specimens of S.A.P.-type alloy (Al-1.2∼12.7 wt%Al2O3). The extruded alloys tend to show a single ⟨111⟩ fibre texture, the degree of which decreases with an increase of the Al2O3 content. On the other hand, the rolling texture of low oxide content alloys is best described as {110}⟨447⟩, and the preferred orientation parallel to the rolling direction tends to change from ⟨112⟩ to ⟨111⟩ with increasing oxide content. These textures differ from those of pure aluminium, in which the hot-extrusion texture is ⟨111⟩+⟨100⟩ and the cold-rolling one is {110}⟨112⟩+{112}⟨111⟩. The difference was discussed in the light of the slip system and the crystal rotation.
