The behavior of individual grain during plastic deformation is affected by shape and size of grains and the crystal orientations for the grains in polycrystalline. We proposed new diffraction-amalgamated grain-boundary tracking (DAGT) technique, which was developed by combining the grain boundary tracking (GBT) technique and a pencil beam XRD. The method provides a description of the crystallographic orientations of individual grains in polycrystalline material during deformation by 4D (3D + time). In addition, the crystal orientation of each grain in plastic deformed material with high strain rate over 20% is determined by means of this technique. Therefore we conducted the assessment of the void growth during deformation in polycrystalline aluminum alloy based on determination of crystal orientation before and after deformation for each grain by using DAGT technique.
