Abstract

Alliage présentant une meilleure combinaison des propriétés mécaniques et de coulabilité. Il se compose en poids de 3 à 10 % Cr, 10 à 13 % Co, 5 à 6 % Al, 5 à 7% Ta, jusqu'à 2 % Ti, jusqu'à 2,5 % V, 0,5 à 10 % Re, 3 à 7 % W, 0,5 à 2 % Mo, 0,5 à 2 % Hf, 0,01 à 0,15 % C, 0,005 à 0,05 % B, jusqu'à 0,1 % Zr, jusqu'à 1 % Nb, le reste étant essentiellement du nickel et des impuretés éventuelles, l'alliage se caractérisant en outre par le fait que la teneur en Co est comprise entre 11 et 13 % lorsque la teneur en Al est supérieure à 5,5 % ou lorsque la teneur en W est au moins d'environ 5 % et en ce que la phase gamma ' représente 64 à 68 % en volume. Application à la fabrication de pièces pour turbines à gaz.
