Microstructure and Local Texture in Hot Rolled Aluminum

Abstract

Local textures have been determined in the deformed and partially recrystallized substructure of a hot rolled commercial aluminum alloy by measuring individual grain orientations in a TEM. These local textures were compared to the global textures of the bulk material obtained by conventional X‐ray diffraction techniques. Cube oriented nuclei were analyzed and two mechanisms for the development of strong cube textures of hot rolled and subsequently cold rolled and recryslallized aluminum sheet are discussed. These mechanisms are the uniform stability of cube oriented grains during rolling and the generation of cube oriented nuclei by shear strains.
