摘要： 以不同变形量对预先经过热轧和再结晶退火的DC AA 5052直接冷却铸造铝合金板进行冷轧制后，采用X射线衍射和专用软件测试、计算并分析表层、1/4厚度层、中心层的织构极图和ODF图及有关数据，研究板厚度方向轧制织构的变化情况，以为改进轧制工艺、获得板厚度方向的织构织及性能均匀性提供依据。各变形量的试样之表层向1/4层、中心层方向，存在β织构逐渐增强的梯度;变形量逐渐增大到90%的过程中，沿板厚度方向β织构强度的变化梯度逐渐降低、体积分数逐步增大、强度逐渐增大并达到各层基本接近。

Abstract：For improvement the processing and gaining uniformity texture structure and performance the thickness direction of direct chill cast DCAA 5052 aluminum alloy band after first hot rolling with different reduction, the material was annealed at 454 ℃ and then cold rolling with different reduction, we test and examined the texture at surface, quarter and center layer of the sample by use X-ray diffraction method, we calculated the data by use special software and analyses the difference texture at surface, quarter and center layer. The intension gradient of β texture was along the direction from surface to center layer gradually enhance at different reduction sample. For β texture, the intension gradient was along the direction from surface to center layer gradually reduce, the volume fraction gradually augment and the intensity gradually were almost equal with the cold rolling reduction increased from 0% to 90%.
