Analyse des hétérogénéités de microstructure et de microtexture héritées par transformation de phase β→α dans des pièces massives en alliage Ti-10V-2Fe-3Al : influence sur la dispersion des propriétés mécaniques

Analyse des hétérogénéités de microstructure et de microtexture héritées par transformation de phase β→α dans des pièces massives en alliage Ti-10V-2Fe-3Al : influence sur la dispersion des propriétés mécaniques

Les alliages de titane β-métastables comme le Ti-10V-2Fe-3Al se substituent progressivement aux alliages α/β dans les applications aéronautiques du fait de leur résistance spécifique améliorée. Leurs microstructures d'emploi sont cependant complexes et multi-échelles, constituées d'une mat...
