Texture study of an AA5083 processed by Repetitive Corrugation and strengthening

5xxx series aluminum alloys are widely used due to their corrosion resistance and weldability. These alloys exhibit interesting behavior when subjected to severe plastic deformation (SPD). Different SPD techniques allow the processing of materials in sheet forms, such as Repetitive Corrugating and Straightening (RCS) and Cumulative Roll Bonding (ARB). In this work, sheets of the aluminum 5083 alloy were processed by RCS up to 2 passes. The objective was to study the microstructural evolution of the AA5083 under heat treatment and plastic deformation processes, with the aim of finding a good balance between the yield strength and ductility. The microstructure changes and the mechanical effects of the process were studied by X-ray diffraction, Inverse Pole Figures, EBSD, and tensile test. The results showed the obtention of characteristic recrystallization and deformation textures (cube and brass component); in particular, the brass component decreased to ∼10 % due to the RCS process. The first RCS pass obtained the best balance between yield strength-ductility (σy = 170 MPa and maximum elongation ∼ 8%). With the results obtained, it was concluded that the microstructure and the mechanical properties of the processes alloy were determined by the accumulative dislocations density, which stopped the cube texture progression, microstructure stabilizing the microstructure, regardless of the work hardening.
