Structures and properties in solidification processes

Development of metallic and polymer materials by solidification from liquid state

Establishment of links between structures and chemical segregation resulting from the solidification step and later forming properties or final properties of the materials.

Objective : control of all of the parameters of all of the processes in forming by solidification to acquire the desired material properties

Fields of research : - solidification of metallic alloys - crystallisation of polymers - precipitation in solid state in metallic alloys


Research activities concern all elaboration processes (continuous flow or ingots, atomisation) and material forming (thermal processing and thermomechanical effects) and forming operations of polymers concerning the relation between crystallisation/flow.


Parallel and sequential calculation capacities with about 10 parallel calculators with different architectures including one new cluster with 500 processors installed in 2008.

Microscopy : - optical transmission microscope (with microtraction device, film micro-compression, static crystallisation, in shear and in elongation) - inversed metallographic optical microscope Olympus PMG3

Scanning electron microscope : - environmental (Philips XL30 ESEM LaB6), heating plate Oxford 1500C, automatic EBSD with digital camera and Peltier effect plate Philips - Jeol 35CF - transmission and scanning electron microscopes (CM12 TEM/STEM Philips) with heated object holder 600C

Spectrometers : - EDX (Oxford/Inca on MEB Philips XL30 ESEM), (Tracor/Noran on MEB Jeol 35CF) - XPS (Riber MAC2) - static SIMS at flight time [ToF-SIMS] (PHI TRIFT I)

Infrared (Fourier transformed, microscope) - X-ray: diffractometer (X'pert Pro), texture goniometer, Debye Scherrer chamber

Physical measurements : - small angle light diffusion - moulding goniometer - rugosimeter 3D - image analyser (Visilog 6.3) - machine for measurements of thermal exchange coefficients - enthalpic differential analyser (DSC Perkin Elmer) - measurement system (deformations, displacement and thickness) by image correlation (ARAMIS system) - non-contact measurements, flow and deformation visualisation : - machine tools with observation windows (injection cast with transparent walls, pipes) - Doppler laser anemometer (Dantec) - flow birefringence - high speed camera (125 to 2500 images/s) - videometric extensometer - mechanical properties : - hardness, hot and cold, micro hardness, macro hardness - furnace for thermal processing, vacuum and under atmosphere (1200C)
