Effect of Cube Texture on the Planar Anisotropy in a Novel Al-Mg-Si-Zn Alloy

Journal Article


Abstract


  • A new Al-Mg-Si-Zn alloy designed for automotive outer panel was trial-produced with industrial procedure. The final product shows a strong planar anisotropy. X-ray diffraction analysis shows such strong anisotropy is caused by the dominating cube texture component in the final product. The reason for such high cube texture component was investigated by tracing texture evolution starting from the hot roll slab(HRS). It is found that certain cube texture components already exists in the hot rolled slab. The strength of cube texture component shows as a wavy change through the following 1st cold rolling, inter-annealing, 2nd cold rolling and solution treatment. This study shows that the cold rolling in the laboratory can well represent the texture evolution during the industrial production. The results obtained by lab rolling hints that change of second cold rolling reduction has weak effect on the planar anisotropy, when the gauge of hot rolled slab and final sheet are fixed.
