Physique du solide, plasticité, diffusion-réactivité, fragilisation par l’hydrogène, nano-structures.
A parti d’une réflexion dans le domaine de l’interaction entre les mécanismes de plasticité et la réactivité de surface nous offrons un nouveau regard sur les mécanismes de corrosion sous contrainte et de fragilisation par l’hydrogène. Les couplages multiphysiques intervenant à l’interface liquide/solide et l’étude des mécanismes de plasticité restent nos deux principales orientations de recherche. Parmi les sujets abordés nous citerons : le rôle de l’état métallurgique sur la diffusion et le piégeage de l’hydrogène dans les métaux, les problèmes de transition d’échelle en diffusion appliqués aux microstructures hétérogènes, l’hétérogénéité de la déformation plastique, …
