Thèmes de recherche

Research topics: Precipitation, ordering, interfacial segregation, radiation effects, effects of intense deformation in metallic alloys (steels, nickel-based alloys, titanium-based, copper-based, aluminium-based, amorphous metal...) Magnetic materials: relationship local structure - microstructure - magnetic properties (iron-rare earth alloys, permanent magnets, amorphous metals, films and multilayers, nanophased alloys) Microelectronic, physic of components, characterization and simulation (reactive diffusion to electrical contacts, redistribution of dopants after ion implantation) Numerical simulations of magnetic structures (phase transitions, hysteresis cycles ...) and the kinetic of phase transformations in alloys (precipitation, ordering, influence of magnetism) Development of laser atom probe tomography, laser-matter interaction in femto-second regime, physic of particle detectors, mass spectrometry, field effect High temperature oxidation of metals and alloys, atmospheric or dry corrosion, surface analysis, nitriding steels, oxide films and coatings Analysis of nonlinear behaviour of materials and structures under complex loads (cyclical and multiaxial loads, thermo-mechanical-metallurgy interactions)
