Abstract

Les aluminiures de nickel et de fer qui sont à base de Ni2A1 et présentent une teneur significative en fer, on ajoute de l'hafnium, du bore, du carbone et du cérium pour donner des alliages à base de Ni3A1 qui peuvent être fabriqués à des températures plus élevées que les alliages semblables antérieurement étudiés et mis au point. Une addition supplémentaire de molybdène améliore la résistance à l'oxydation et la résistance au fissurage. Ces alliages présentent des avantages de ductilité, d'aptitude à la fabrication à chaud, de résistance mécanique et de résistance à l'oxydation.Nickel and iron aluminides which are based on Ni2A1 and have a significant iron content, hafnium, boron, carbon and cerium are added to give Ni3A1 based alloys which can be manufactured at high temperatures. higher temperatures than similar alloys previously studied and developed. Further addition of molybdenum improves the resistance to oxidation and resistance to cracking. These alloys have advantages of ductility, hot workability, mechanical strength and oxidation resistance.
