The aim of the HoTMiX research project is to provide a deep understanding of the relationships between the nonlinear mechanical response of oxide materials at very high temperatures and their microstructure at the nanoscale.

HoTMiX - Micromechanical behaviour of nanostructured oxides at very high temperature
The global thermomechanical behaviour of polycrystalline ceramic materials cannot be predicted from the fundamental properties of corresponding crystals, nor can it be understood solely at the macroscale. Solid-state phase transitions and anisotropy of the thermal expansion simultaneously result into the appearance of nanosized crystals and of huge stresses, heterogeneously distributed among crystals. This can result in a multiscale and complex crack network at scales ranging between a few nm and a few mm. The aim is to provide a deep understanding of the relationships between the nonlinear macroscopic mechanical response of oxide materials at very high temperatures and their microstructure at the nanoscale.
