Matériaux complexes pour l’énergie

Présentation

Matériaux complexes pour l’énergie

Nous visons à modéliser les propriétés thermiques et mécaniques des matériaux d’usage dans le domaine des énergies, de structure atomique et chimique en général complexe (alliages multi composants présentant des phases variées tant du point de vue cristallographique, que chimique ou magnétique, alliages à haute entropie, …), qui sont amenés à travailler sous des sollicitations extérieures parfois agressives (température, pression, irradiation) et sur des temps longs (vieillissement des aciers).
Ces propriétés sont essentiellement pilotées par la diffusion combinée des éléments chimiques et des défauts cristallins, dont la modélisation est encore impossible par le seul recours aux calculs ab initio.
