‘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, …
