Compétences

Mots clés : Transformation de phase ;  Microstructure ; Texture ; Microscopie électronique ; Orientation cristallographique, Analyse tri-dimensionnelle.

Mes travaux de recherche au sein de l'équipe 3TAM  portent sur les aspects suivants :

1.  Contribution au développement de nouvelles approches en microscopie couplées aux techniques de mesures d'orientations individuelles - acquisition des données et post traitement avancé (développement de l'EBSD 3D en mode statique, développement de l'acquisition de clichés SACP sur MEB-FEG dernière génération pour l'A-ECCI, reconstruction de microtexture parente et outil d'analyse des transformations de texture).

2.  Poursuite des études sur l'analyse des microstructures/microtextures de transformation de phase des aciers à très haute résistance (thèse Elodie Boucard – Master et Thèse Meriem Ben Haj Slama)

3.  Poursuite des études concernant les hétérogénéités de texture dans des pièces industrielles en alliage de titane – Influence sur les propriétés mécaniques (Travaux de thèse de Christophe Buriette et Mathieu Salib, Stage Master Maria Rita Chini et thèse  à venir)

Je participe à l'ANR ASZTech : Alternative Sustainable Zirconia Technology (for glass melting) pour l’étude des microtextures de solidification des matériaux réfractaires électrofondus à haute teneur en zircone (recrutement de Taylan Örs en post-doc à partir de septembre 2014).

Je suis également responsable scientifique du service de microscopie électronique à Balayage du Saulcy (3 MEB +1 FIB équipés de systèmes EBSD/EDS) avec une équipe d'un ingénieur de recherche et d'un technicien.
