WELCOME, Visitor!

The Extreme Micromechanics Research Group is at Laboratoire Georges Friedel in Saint-Étienne, France. Our team specializes in small-scale deformation experiments, pushing the frontiers of materials science by investigating mechanical behavior under both ambient and extreme conditions. Through cutting-edge in situ techniques within scanning electron microscopes and advanced synchrotron-based experiments, we provide high-precision insights into material properties. Our research is complemented by strong collaborations in simulation and modeling, enabling a deeper understanding of deformation mechanisms. Committed to innovation and scientific excellence, we work closely with academic and industrial partners to tackle complex challenges in micromechanics.

CURRENT RESEARCH TOPICS

MICROSTRUCTURE
CHARACTERIZATION

 

We apply various techniques to describe the structure of solids.

FIB MACHINING

 

We empoy focused ion beam to create samples for mircomechanical testing.

HYDROGEN CHARGING

 

We are working on in situ hydrogen charging techniques to combine mechanical and chemical characterization at the same time.

3D RECONSTRUCTION

 

We use serial sectioning or tomography techniques to image a 3D volume of the sample. 3D rendering helps with visualization.

HR-EBSD

 

High (angular) resolution electron backscatter diffraction is our main speciality to characterize geometrically necessary dislocations evolving as a result of external loading.

MICROMECHANICS

 

We are performing various test on the micron scale: pillar compression, cantilever bending, pillar splitting, tension bar pulling, nanoindentation mapping, etc.
