Orientation Determination

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

Creep Loading

Considerable structural inhomogeneity and anisotropy were found even after eight ECAP passes in high purity aluminium and the creep loading of ECAP material at 473K, 15MPa resulted in scattered fracture times ~ 20-60 hours. The structure revealed by orientation imaging microscopy with different disclination bounds was analysed by stereological methods. The effect of inhomogeneity and grain orientation on the creep fracture time was assessed.
