‘3D’ Project and Cross-Beam Microscopy

Ex. Dual-Phase steels (PhD B. Krebs LEM3-ARSA)

Fractures within martensite or at α/α’ interfaces

3D topology of martensite (serial polishing)

3D distribution of stress/strain (FEM modelling) http://dream3d. 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 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

• Micro-machining of thin foils for TEM analyses (possibility of selecting ROI); samples for micro-mechanical testing, …
