The effect of intermediate annealing (IA) on texture evolution and plastic anisotropy of an Al-Mg autobody sheet was investigated. The formation of annealing textures after two kinds of final heat treatments was discussed with the aid of microstructural characterization. The results showed that the IA treatment had obvious influences on the final annealing texture as well as the resulting plastic anisotropy. It led to relatively lower recrystallization extent and stronger retained rolling orientations in the sheets after final heat treatment. The final annealing textures were very weak due to the dominant influence of particle stimulated nucleation. The other orientations occurring can either be attributed to genuine recrystallization or to recrystallization in situ. As a result of good suppression of the cube and rotated cube orientations, a good combination of normal anisotropy and planar anisotropy was achieved in the sample with IA and after O treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
