| Abstract Scope |
In this talk, we discuss the results of high orientation precision 3D-EBSD from serial sectioning with spherical harmonic indexing. We highlight various difficulties that arose from the increased orientation precision, such as an increased sensitivity to surface preparation quality or minor sample alignment issues, along with the solutions we implemented to resolve these issues. We also demonstrate registration of the 3D-EBSD data with multiple other data modalities, including zero-tilt optical and backscattered electron imaging, as well as near-field and far-field high-energy diffraction microscopy. We also demonstrate analysis of fine microstructural details in specific grains using electron channeling contrast imaging, further extending the level of detail that can be obtained in three-dimensional microstructural analysis. |
