研究了不同冷轧工艺参数的深冲铝板坯（wA1＞99．75％）的显微组织、织构，测定了不同方向的力学性能；由D－500全自动X射线衍射仪建测极图，按Bunge的方法计算取向分布函数（ODF）；通过透射电镜观察变形显微结构．结合冷轧变形亚组织结构和织构特征，讨论了位错胞结构与板坯塑性变形和力学性能的关系，以及对板坯塑性各向异性的影响，预测材料深冲性能．分析认为，材料力学性能决定于变形组织结构和织构，随冷变形量增大，位错缠结胞变形并发生取向排列形成显微带，使材料产生力学性能各向异性及加工硬化．本研究显微组织和织构特征及力学性能分析结果表明，接近50％冷轧变形量的板坯中变形亚组织均匀、多种织构混存，有利于降低材料深冲制耳率．并经工业制罐试验验证．
The microstructures and textures of deep-drawn aluminum slabs (wA1> 99.75%) with different cold-rolling parameters were studied, and the mechanical properties in different directions were measured. The polar diagram of D-500 automatic X-ray diffractometer The orientation distribution function (ODF) was calculated according to the method of Bunge. The deformation microstructure was observed by transmission electron microscope. The relationship between dislocation cellular structure and plastic deformation and mechanical properties of slab, as well as the influence on plastic anisotropy of slab, and the prediction of material deep drawing performance are discussed. The analysis shows that the mechanical properties of materials depend on the deformation structure and texture. With the increase of cold deformation, the dislocated entangled cells deform and align to form microstrips, which make the material produce mechanical anisotropy and work hardening. The results of microstructure and texture analysis and mechanical property analysis show that the deformed sub-structure in the blank with the cold-rolling deformation of nearly 50% is uniform and the various textures coexist, which is beneficial to reduce the ear-drawing rate. And tested by industrial cans test.
