MIMEX : Expertises and equipments

Microstructural examinations

• Scanning electron microscopy : microstructures, fracture surfaces, microtextures in EBSD
• Transmission electron microscopy : microstructures, diffraction phase identification, deformation microstructures
• Tomography, Laminography, FIB, X-ray diffraction

Complex mechanical tests over a wide temperature range

• Under controlled environment (air, vacuum, atmosphere, humidity, etc.)
  • Monotonic traction or compression in quasi-static or dynamic, uniaxial or biaxial
  • Complex cyclic tests simulating real loading (ex : turbine engine cycle of a turbine blade)
  • Cracking tests : thermo-mechanical fatigue, creep, fracture, tenacity
• Correlation of digital images (2D or 3D), including high temperature

Modeling and numerical integration of models

• Development of robust models based on large test bases on all studied materials
• Development of physically based models taking into account phenomena ranging from physico-chemistry to macroscopic damage
• Modeling of damage in isothermal and anisothermic conditions in close connection with the SIMS and SIP poles

Specific technical resources

• Mechanical testing machines : traction, compression, creep, relaxation, fatigue, etc.
• Thermal fatigue benches (Joule effect and radiant heating)
• Static or cyclic oxidation bench without load (tube ovens)
• Enclosure for performing vacuum tests (cracking, fatigue, etc.)
• Monitoring of damage / cracking by electrical or optical method
• Development of in situ mechanical tests for tomography / laminography
