‘3D’ Project and Cross-Beam Microscopy Textured macrozones in a HT forged Ti-alloy Ex. Dual-Phase steels ( PhD B. Krebs LEM3-ARSA ) Fractures within martensite or at α/α’ interfaces 3D topology of martensite (serial polishing) http://dream3d. 3D distribution of stress/strain (FEM modelling) bluequartz.net/ • Ultimate mechanical properties (formability, fatigue, …) depend on the 3D phase topology AND crystal orientation distributions • Microstructure development can only be undestood/modeled from the knowledge of 3D 7 distributions of defects (GB, dislocation cells, …)

‘3D’ Project and Cross-Beam Microscopy • Acquisition and analysis of High-Resolution 3D images of poly-phased microstructures • Acquisition and analysis of High-Resolution 3D EBSD maps • Development of the ‘static’ 3D EBSD configuration in collaboration with Zeiss, Brucker and Newtec. • Development of dedicated tools to analyse 3D maps GNDs’ distribution • Micro-machining of thin foils for TEM analyses (possibility of selecting ROI); samples for micro-mechanical testing, … 8
