Recrystallization textures of a cross-rolled aluminum alloy

The textures in cross-rolled FCC metals and alloys have been frequently reported to be of the type {1 1 0}〈2 2 3〉 which is independent of the stacking fault energy of the material. In Al-3%Cu alloy the cross-rolling textures, however, are found to be different and depend on the prior heat-treatment of the alloy. Upon annealing at 400 °C, the cross-rolling textures of naturally-aged and over-aged alloys are not retained as in the case of α-brass but transform to two different recrystallization textures. The difference may due to the dependency of the operation slip systems on the deformation path and the type of precipitates in the aging treatment.
