Abstract

Cette invention se rapporte à l'usinage sous pression de métaux et d'alliages, notamment à l'usinage d'alliages à base d'aluminures de titane TiAl (phase η) et Ti3Al (phase α2) obtenus par coulage. Cette invention concerne également un procédé de frittage, et peut être utilisée afin de produire des tôles et des feuilles ayant une structure réglementée. Ce procédé consiste à utiliser en qualité d'ébauche de départ une ébauche ayant une structure à granulation fine préalablement préparée. Le laminage en tôle ou en feuille d'une épaisseur prédéterminée et présentant des grains d'une certaine taille se fait dans la plage de vitesses de déformation 10?-3 à 10-1 sec.-1¿ et dans une plage de température T* à Te ° C où T* varie de préférence de 400 à 700° C tandis que Te représente la température de conversion eutectique. Ce laminage s'effectue en une ou plusieurs étapes au cours de N passages dans des conditions isothermes ou quasi-isothermes. La température T¿i+1? de chauffage de l'ébauche à chaque étape suivante est choisie selon la relation Ti+1 = Ti où Ti représente la température de chauffage de l'ébauche à l'étape précédente, étant entendu que pour la première étape Ti = To où To représente la température de déformation lors de la dernière étape lors de la production de l'ébauche par laminage. On peut encore respecter la relation Ti+1 = Ti + ΔTi+1 ou Ti+1 = Ti - Δti+1 où Δ Ti+1 est choisi d'après les conditions de croissance tolérée des grains tandis Δti+1 est choisi d'après les conditions de déformabilité ou de déformabilité et de réduction d'oxydabilité des alliages.
