| 摘 要： | 非均匀变形在材料工程领域是一个有趣的问题。同步辐射成像技术通过跟踪多晶体铝合金的显微组织的特性，提供了局部应变的3D分布图。为了更加深入地分析非均匀的过程，开发了三维X射线衍射分析技术。它利用跟踪晶界获得的信息（GBT），描述了三维空间中新的晶体取向测试技术。

| Abstract: | Development of inhomogeneous deformation is an interest matter in material engineering. Synchrotron radiation tomography provides 3D distribution map of local strain in polycrystalline aluminum alloy by tracking microstructural features. To perform further deep analysis on development of inhomogeneous deformation, crystallographic grain orientation is necessary. Three-dimensional X-ray diffraction technique was developed. A new crystallographic orientation measurement method was described in 3D space, utilizing grain boundary tracking （GBT） information. |
