Abstract：

For the problems of sever deformation for heat-treated parts after spinning of large aluminum alloy cylinder with cross-stiffeners, a new process route of solid solution-warm spinning-artificial aging was designed, and the spinning tests of 2219 aluminum alloy cylinder with cross-stiffeners by spinning-solution aging (T6) and solution-warm spinning-artificial aging (T8) were completed. Then the mechanical properties and microstructures of T6 and T8 materials were analyzed respectively. The results show that the quenched tube is processed by warm spinning at 180-200 ℃, the samples have higher dimensional accuracy after aging, and compared with the T6 samples, the tensile properties of the panel and the Vickers hardness of the panel and stiffener for the T8 samples were improved, which is due to the finer grains micro-structure and more precipitation strengthening phase obtained during aging. Thus, the process method provides technical support for the development of large aerospace cross-stiffened cylinder manufacturing.
