Research > Microstructures and Processing Department
The microstructure and processing department pursues its research within the framework of significant projects concerning metal alloy work-up :
A European project "Through process modeling of Al rolling and extrusion" (VIRFAB) is carried out in collaboration with four aluminium industrial companies, four academic partners (Aachen,Trondheim, Sheffield and Delft) and two research centres (Stockholm and Sintef). The project "Friction Stir Welding" on an AA2024 alloy for applications in aeronautics. Thermo-mechanical treatments of ferritic steels with Cr, of Ni 718-based super-alloys and of Zircaloy. Grain boundary mobility in aluminium (a project supported by the Rhone-Alpes region in collaboration with the Materials Department, Riso, Denmark). Cutting 6xxx aluminium alloy sheets for car bodies. Heterogeneities of deformation when forging TA6V parts. Textures and mechanical anisotropy of extruded AA 7xxx sections for aeronautics. EBSD measurement of local deformations in springs made from 718 for nuclear power plants. Characterization of materials for micro-electronics, and in particular X-ray characterization of the surface quality of single-crystal aspheric lenses. Controlled metal alloy cross forging to obtain materials with ultrafine microstructures. Calculations of 3D deformations in thin rolled sheets (VAI/CLECIM)
