摘　　要：为了对铝合金板轧制技术发展提供依据,采用X射线衍射仪测试极图并使用专用软件计算织构的ODF,研究了热轧后经过454℃×4h预先再结晶退火处理的5052双履带连续冷却铸造铝合金板,进行不同变形量冷轧后自表层至心部层的织构分布状况。冷轧制后变形量小于40%的试样,存在织构强度由表层向中心层提高的变化梯度。变形量大于56.1%的试样,β织构的增加主要是来自剩余位向转变量随变形量的增加;主要织构β较强、Goss和剩余位向较弱,各层之间的织构状态接近。For improvement of the processing and gaining uniformity texture structure and performance of direct chill cast CCAA 5052 aluminum alloy band after first hot rolling with different reduction, the material was annealed at 454 ℃ and then cold roll- ing with different reduction was conducted, the texture at surface, quarter and center layer of the sample was tested and exam- ined by X-ray diffraction method, the data calculated using special software and the difference of texture at surface, quarter and center layer was analyzed. There existed an elevated gradient of intensity from surface layer to center layer after cold rolled with less than or equal to 40% reduction, The main texture of 13 is stronger mainly due to transformation from remainder exposure, while the goss and remainder is infirm, the state of texture at each layer is close to each other after cold rolling with reduction high than 56.1 %.
