Using advanced orientation imaging scanning electron microscopy to reveal subtile microstructural details after martensitic transformations and dendritic soldifications. Pascal Thome develops new software algorithms to characterize specific microstructural feature by electron backscatter electron diffraction (EBSD) in the scanning electron microscope (SEM). He investigates fundamental crystallographic principles and reveals special morphological features after martensitic phase transformations in iron based alloys. Here moreover develops a high resolution EBSD method, which allows to precisely describe crystal mosaicity in single crystal Ni-base superalloys. This part of the work is embedded into the collaborative research center SFB/TR 103. The new method is based on a cross-correlation procedure and provides an improved high angular resolution. In parallel and as another feature of his new method, Pascal Thome applies new ways of visualizing different types of orientation differences, which allow an intuitive appreciation of crystallographic microstructural features
