| Research Abstract |
The three-dimensional x-ray diffraction (3DXRD) microscopy is a novel method for non-destructively three-dimensional observation of crystal orientation and stress of each crystal grain in polycrystalline metallic materials. It may be often difficulty to observe ideal polycrystalline deformation in a typical measurement technique due to the limit of number of grains in an observed cross section. In this study, the approach named scanning 3DXRD which allows us to observe specimens with as a large number of grains as possible in the cross section is proposed. The principle of the scanning 3DXRD that identifies the grain at an arbitrary point in a specimen was experimentally proved. The BCC slip deformation of a polycrystalline ferrite was observed from in-situ three-dimensional mapping of orientation under a tensile load.
