系统研究了6111铝合金在热轧和冷轧变形过程中的力学性能、织构和显微组织的演变规律。结果表明，冷轧和热轧对该合金的拉伸性能有显著影响。剪切织构和再结晶织构主要在热轧变形过程中形成，轧制织构主要在冷轧变形过程中形成。晶粒细化机制主要取决于轧制工艺。热轧过程中，剪切带移动和再结晶是主要的晶粒细化机制;冷轧过程中，位错缠结是主要的晶粒细化机制。再结晶织构和剪切织构对延伸率各向异性有影响，而轧制织构对屈服强度各向异性有显著影响。
The mechanical properties, texture and microstructural evolution of a 6111 aluminum alloy during hot rolling and cold rolling deformation were systematically investigated in this article. The results show that cold rolling and hot rolling have significant effects on the tensile behaviors of the alloy. The shear texture and recrystallization texture mainly formed during the hot rolling deformation process, while the rolling texture mainly formed during the cold rolling deformation. The grain refinement mechanisms depend significantly on the rolling process. Movement of shear zone and recrystallization are the main grain refinement mechanisms during the hot rolling process, while dislocations tangling is the main grain refinement mechanism during the cold rolling process. The recrystallization textures and shear textures affect the anisotropy in elongation but the rolling textures affect significantly the anisotropy in yield strength.
