There is large difference of strain between surface and inside materials in strain singular field. It is important to analyze strain field material in 3D/4D, because almost all of grains exist inside material. We use technique amalgamating a transmission X-Ray diffraction (XRD) experiment with grain boundary tracking (GBT) that has been developed by the present authors. This technique combines X-ray micro tomography (CT), this novel technique which is called the diffiaction-amalgamated grain boundary tracking (DAGT) technique, provides accreted crystallographic deformation of individual grains dining deformation of material. It makes non-destructive and in-situ characterizing of materials possible up to plastic defamation near failure event. We success to realizes strain during tensile test and grain orientation before tensile test by using DAGT technique in previous study. It is necessary to realizes grain orientation during tensile test to analyze crystallographic deformation immediately before destruction. For this raison, technique ofthe addition for DAGT was developed in this research.
