The investigation studied the plastic anisotropy of the severely-deformed Al-Mg-Si alloy by considering texture changes. The sample deformed via asymmetrical rolling under cross-shear condition was annealed at 598 K where recrystallization was in progress. It is found upon annealing that the intensity of Cube ({001} < 100 >) was comparable to those of plane-strain components while the intensities of shear components remained constant despite their instabilities in the recrystallization regime. After annealing, the average Lankford value ((r) over bar) of the present sample was close to a unity whereas the in-plane anisotropy (Delta r) decreased, resulting in nearly isotropic characteristics of Al-Mg-Si alloy.
