Thomas Gheno

Présentation

Mes activités visent à mieux comprendre les évolutions chimiques et microstructurales des matériaux métalliques à haute température ; à prévoir leur comportement en service ainsi que leur durée de vie ; à développer des matériaux plus performants. Elles s’appuient principalement sur la métallurgie et la thermodynamique ; elles combinent travaux expérimentaux et numériques.
