Offre de thèse – IRCER Limoges

Selection of materials (High Zirconia fused-cast refractories, Aluminium Titanate based refractory material) in close collaboration with St-Gobain and Safran;
✓ Development of specific techniques for the mechanical characterization of refractory materials at high temperature, in particular involving Digital Image Correlation (DIC);
✓ Characterization of high temperature mechanical properties (elasticity, thermal expansion, stress/strain laws, damage monitoring, thermal shock behaviour) of these different materials, with a particular attention on non-linear behaviour during tensile and compressive loadings;
✓ Interpretation of the obtained results in relation with microstructure evolution versus temperature to be investigated by classical laboratory means but also by more specific devices at synchrotron radiation sources in collaboration with other partners of HoTMiX;
✓ Managing micro-mechanic simulations using Discrete Element Method (DEM).
