摘要：The textures induced by deformation processes of different crafts in air-condition used aluminium 1050H19 foils were measured by using X-ray goniometer. Combining with TEM analysis, effect of texture on deep-drawing property was discussed. It is show that deformation textures in the specimens, on which four types of rolling-crafts are carried out respectively, are all typical Cu components, and recrystallized R-, Cube-texture don't exist. Cu-texture is still the predominant component with different orientation density according to different rolling-craft. To specimens which are prone to cracking, their orientation densities of Cu-textures are higher, their textures are stronger and they contain P- and Goss-texture, which are harder to be deformed. The analyses indicat that with the decrease in the rate of reduction/rolling-time and the execution of intermediate holding, textures that are harder to be deformed are eliminated and orientation density of Cu-texture is weakened. Thus, deep-drawing property of aluminium foils is improved.
