Effect of Fiber Orientation on Microstructure and Texture Evolution During the Cold‐Rolling of Al–Mg–Si Alloy

A material with a strong double fibrous texture is subjected to rolling with various deformation paths—unidirectionally and with 90° rotations about the normal direction (cross‐rolling). Additionally, the orientation of the initial fiber is manipulated to force unlikely grain rotations. The purpose of these procedures is to study the dependence between crystallographic and morphological texture changes caused by the rolling. Microstructure observations show that deformation mechanism responsible for the final microstructure depends on the initial fiber orientation. The crystallographic texture is related to the deformation mode and leads toward expected orientations; however, the initial grain boundaries alignment has a strong impact on the final microstructure. Unidirectional rolling results in typical orientations along the β‐fiber in all investigated cases. The texture created during the more complex deformation path with inset rotations follows the geometrical constraints for fourfold symmetry, even if this required unlikely rotations toward the α‐fiber.
