Development of three-dimensional orientation analysis method by using high-flux synchrotron X-ray

为了对金属等多晶材料进行变形和断裂分析，发展了一种非破坏性地测量样品中晶体取向的方法。利用欧洲和日本的同步辐射装置研究了铝合金的取向图。通过对晶粒取向图和变形后应变分布的三维比较，证实了非均匀变形取决于晶体取向。

For the purpose of deformation and fracture analysis in polycrystalline materials like a metal, the method that measure crystallographic orientation within a sample non-destructively has been developed. The orientation maps of an aluminum alloy were investigated using European and Japanese synchrotron radiation facilities. Inhomogeneous deformation depending on crystallographic orientation was confirmed comparing grain orientation map with strain distribution after deformation in three-dimension.
