【 摘 要 】

The goal of this work was to study the asymmetric rolling process using the Finite Element Method (FEM) coupled with the deformation model of polycrystalline material. The Leffers-Wierzbanowski (LW) model was selected to be implemented into FEM. This implementation enables a study of heterogeneous plastic deformation process, like asymmetric rolling, taking into account its crystallographic nature. Our aim was to examine the crystallographic texture and mechanical properties of asymmetrically rolled aluminium 6061. The simulation results are compared with experimental textures determined by X-ray diffraction. The advantages of asymmetrical rolling over symmetrical rolling are reduced rolling normal forces and rolling torques, improvement of microstructure and producing the homogeneous crystallographic texture.
