ADAPTED KNOWHOW

MATEIS has expertise in:
▪ Formulating  / exploring innovative processes for formulating ceramics, metals, polymers and hybrids and their applications;
▪ Characterising / developing observation techniques in environmental mode or in situ using electronic microscopy; optimising three dimensional imaging techniques (tomography);
▪ The instrumentation / design of in situ tests on the evolution of microstructures in service: thermomechanics, chemistry, and in living media (medical systems);
▪ Multiscale modelling and simulation / analysis of tests, testing ideas, explaining and reproducing a change observed experimentally and fully simulating the behaviour of a microstructure.

• Three dimensional characterisation of materials by X-ray tomography: rebuilding materials at the micron and millimetre scales
  (Transport, Energy, Health and fault detection)
• Gleeble thermomechanical simulator: simulation of rapid transformation (welding, continuous furnaces, etc.)
  (Transport, Energy)
• Rapid material sintering methods: forming and sintering using different complementary techniques.
  (Transport, Energy, Health)
• Electronic microscopes: structural and chemical characterisation of materials, 1nm to 1µm
  (Materials, Transport, Energy, Health and fault detection).
