Texture and mechanical anisotropy of ultrafine-grained Al alloy AA6016 produced by accumulative roll bonding — •Werner Skrotzki1, Ingwar Hünsche1, Juliane Hüttenrauch1, Heinz-Günter Brokmeier2, Heinz Werner Höppel3, and Irena Topic3 — 1Institut für Strukturphysik, Technische Universität Dresden — 2GKSS Forschungszentrum, Geesthacht — 3Lehrstuhl Allgemeine Werkstoffwissenschaften, Universität Erlangen-Nürnberg
The texture of ultrafine-grained Al alloy AA6016 produced by accumulative roll bonding (ARB) has been measured by neutron diffraction. The starting texture consists of a strong cube component. During ARB this texture breaks down and a texture typical for rolling of face-centred cubic metals with high stacking fault energy develops. The texture after 8 ARB cycles is characterized by the beta-fibre with the Cu component dominating. Moreover, the rotated cube component forms. This component is typical for simple shear which during rolling takes place in the surface layer of the sheets. Based on the Lankford parameter calculated the mechanical anisotropy of the advanced metal sheets will be discussed.
