金属管通常表现出沿沿着圆周和贯穿壁厚的不均匀性。采用同步辐射衍射的局部织构分析和中子衍射的全局织构分析来描述与壁厚相关的织构变化。测试样品是外径为140 mm且平均壁厚为10 mm的SF-Cu管。纹理由立方体组件{001}主导<100>。其他次要成分为旋转立方体{013}<100>、戈斯{011}<100>、铜{112}<111>、黄铜{110}<112>、S {123}<634>。在壁厚上的纹理梯度示出了立方体分量的锐度的显著变化。其他组件显示只有很小的变化。比较在最大壁厚和最小壁厚处获得的样品，可以看出壁厚对全局纹理以及纹理梯度具有影响。另一个有趣的结果是，全球纹理直接测量中子和平均全球纹理，计算出的一组本地测量同步辐射衍射，同意令人惊讶的是，尽管他们不同的分辨率。
Metallic tubes usually show heterogeneities along circumference and through wall thickness. Local texture analysis by synchrotron diffraction and global texture analysis by neutron diffraction was used describing texture variations related to the wall thickness. Test sample was an SF-Cu tube with outer diameter of 140 mm and an average wall thickness of 10 mm. The texture is dominated by the cube component {001} <100>. Other minor components are rotated cube {013} <100>, Goss {011} <100>, Cu {112} <111>, brass {110} <112>, S {123} <634>. The texture gradient over the wall thickness shows a remarkable variation of the sharpness of the cube component. Other components show only little variation. Comparing samples obtained at maximum wall thickness and at minimum wall thickness one can see that the wall thickness has an influence on the global texture as well as texture gradient. Another interesting result is, that global textures measured directly by neutrons and averaged global textures, calculated from the set of local measurements by synchrotron diffraction, agree surprisingly well despite their different resolution.
