Study of Texture in 6016 Aluminum Alloy during Processing

Abstract:

The evolution of texture in AA6016 alloy during processing was systematically investigated. The hot-rolled 6016 plates were cold-rolled to 0.9mm through three different rolling processes. One was directly rolled to 0.9mm, the other two were rolled to 1.8mm and 2.3mm, respectively, followed by intermediate annealing at 360°C for 2h, and then rolled to 0.9mm. Finally, the three kinds of cold rolled plates were performed continuous annealing at 560^oC. The textures and microstructures of each stage were characterized by the X-ray diffraction and electron back scattering diffraction (EBSD) techniques. The results show that the texture of hot-rolled sample is mainly composed of Brass, S and Copper; the relative amount and maximum density changed after 1^st cold-rolling. After intermediate annealing, the Cube and Cube+ND₂₀ texture replace the deformation texture and rise with the rolling reduction. Then the conducting of final cold rolling results in the decrease of Cube and Cube+ND₂₀ component and increase of deformation texture. After the continuous annealing, R, Brass-R, Goss, Cube and Cube+ND20 components are observed. Particle stimulated nucleation (PSN) and nucleation at shear bands dominate the competition of recrystallization.
