Research Abstract	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.
