Abstract

Plusieurs laboratoires et centres techniques ont commencé à travailler sur la possibilité de réaliser des composés multimatériaux via la Métallurgie des Poudres. Dans un tel cas, ce procédé permet d'éviter le problème de l'assemblage et d'obtenir une production aux cotes. Les compressions dynamique (CGV) et conventionnelle sont deux voies possibles qui pourront être comparées grâce à une presse de laboratoire instrumentée pour l'analyse des phénomènes. Pour certaines poudres, la CGV permet d'améliorer les propriétés à vert et de modifier favorablement les conditions de frittage. La compression est suivie d'un frittage conventionnel. Différents types de poudres (poudres métalliques, poudres dures mais également des poudres céramiques) sont utilisés dans ce projet permettant ainsi de proposer de nombreuses applications. Cette présentation montre les premiers résultats obtenus par le groupe de recherche.
