Abstract
In this study, we used the digital-image-correlation (DIC) technique to investigate microstrain distribution after 5% deformation. Electron backscatter diffraction (EBSD) was also investigated in the orientation maps at triple junctions for an aluminum polycrystal after annealing at 360°C for 5, 20, 40, and 80 min, respectively. The results of the strain distribution demonstrated that strong deformation heterogeneities occur in the form of macroscopic shear localizations and that the average orientation spread or misorientation increases during annealing. Further, grain boundary migration was observed even at grain boundaries with the smallest differences in the orientation spread.
