EBSP, Progress in Technique and Applications

To measure grain orientation in SEM with high accuracy a new EBSP calibration software isdeveloped. Grain orientation determination is simply based on marking three zone axes in the liveEBSP. The EBSP-technique has been applied to study misorientation between subgrains in highpurity and commercially pure aluminium. The lattice curvatures, which develop during deformation,increase with the amount of deformation. During annealing the subgrains grow, resulting in anincreased average neighbouring misorientation due to misorientation accumulation.
