Abstract

La présente invention concerne des articles en superalliage de nickel à structure monocristalline. Ce superalliage a une composition particulière et subit un traitement thermique particulier. Les alliages des articles obtenus sont libres de tout élément durcisseur de grains tels que le carbone, le bore, et le zirconium et contiennent seulement une quantité limitée de cobalt De part leur composition, ces alliages possèdent une température de fusion commençante élevée. L'invention est par exemple utilisable pour la fabrication d'aubes de moteurs à turbines à gaz.
