Aeronautical and space systems are composed of high-tech materials subjected to severe environments and stresses.
The mechanical characterisation is carried out within the Laboratory for Mechanical Behaviour of Irradiated Materials (LCMI).
The Speeds of generalized corrosion (uniform corrosion) of metals or alloys which are generally used in aqueous environment depend not only on the material/environment couple, but also on physical-chemical conditions (temperature, concentration of species in solution, fluid velocity,…).
The determination of chemical durability of concrete materials requires the acquisition of experimental data, the understanding and modelling of elementary mechanisms relative to the material hydratation, the chemical reactivity, transport properties and the mechanical impact.
This scientific axis covers the activities related to the research in materials science and more generally in hetero-systems (i.e., interfaces, alloys, composites materials, and confined systems).
Within the Laboratory for light element studies (LEEL, Laboratoire d'Etude des Eléments Légers), research topics are focused on light element behavior in materials, mainly with the help of the nuclear microprobe, a facility remarkably suited for monitoring such elements.
The object of these researches is, through experiments using external tools for irradiation (ions or electrons accelerators) and also by means of simulations, to study the fundamental behaviour under irradiation of a large variety of materials in the context of electro-nuclear generators (metal alloys, glasses, ceramics, polymers).
Studies realised in the group seeks to understand and describe the relationship between the microstructure of a material and its mechanical properties such as its fracture properties for example.
