摘　　要：对热轧铝板的织构进行了X射线反射法剥层测量和X射线透射法直接测量。透射法测量时需要对极图数据作绕轧向转90°的坐标转换。两种方法的对比分析表明,透射法可以直接获得热轧铝板的真实织构,避免了反射法测量时铝板织构不均匀性引起的测量结果偏离整体织构。透射法测量织构过程简捷、准确,有利于发展在线织构检测技术。The texture of hot rolled aluminum plate was measured on decorticated sample by X-ray reflection technique as well as by X-ray transmission technique, in which a 90°coordinate rotation around rolling direction is requested. The comparison indicates that the real texture of the aluminum plate can be obtained directly in the transmission way, which also avoids the possible deviation of measured result based on reflection technique from the integrated texture of the plate because of the texture inhomogeneity. The transmission technique is a simple and accurate way to determine texture, and can be used to develop the technology of on-line texture measurement.
