Abstract

La présent invention a pour objet de fournir un superalliage monocristallin à base de Ni permettant d'améliorer la résistance en prévenant la précipitation d'une phse de TCP à haute température. Ceci est obtenu au moyen d'un superalliage monocristallin à base de Ni ayant la composition suivante : 5,0-7,0 % en poids d'Al, 4,0-8,0 % en poids de Ta, 2,9-4,5 % en poids de Mo, 4,0-8,0 % en poids de W, 3,0-6,0 % en poids de Re, 0,01-0,50 % en poids de Hf, 2,0-5,0 % en poids de Cr, 0,1-9,5 % en poids de Co et 1,0-4,0 % en poids de Ru, le restant étant du Ni et des impuretés ne pouvant être évitées.
