Oxygène interstitiel dans les alliages TiAl : effets sur la microstructure lamellaire, la ductilité et la limite d'élasticité. L'utilisation d'une procédure d'élaboration et de traitement thermique propres nous a permis d'étudier l'influence de l'oxygène interstitiel sur la microstructure et les propriétés mécaniques des alliages Ti50Al48Cr2 à microstructure entièrement lamellaire. Les effets de l'oxygène sur l'alliage ternaire sont significatifs et similaires à ceux observés pour les alliages binaires Ti52Al48, à savoir que la fraction volumique de phase α2, la microdureté et la limite d'élasticité augmentent avec des teneurs en oxygène croissantes alors que la ductilité diminue. Il apparaît alors que l'oxygène interstitiel a un ef...
