Nickel-based alloy powder comprising Y2O3 oxide

Abstract

The present invention provides a nickel-based alloy powder composed of 0.2 to 5% of Y2O3 oxide, the remainder of the powder having the following composition: 9.50 to 10.50% Co; 8.70 to 9.10% Cr; 6.60 to 7.40% W; 4.60 to 5.00% Al; 3.60 to 4.00% Ta; 2.30 to 2.70% Ti; 1.60 to 2.40% Mo; 1.40 to 1.70% Hf; 0.09 to 0.13% C; 0.010 to 0.020% B; 0.03 to 0.07% Zr; 0 to 0.20% Fe; 0 to 0.10% Si, Mn, Cu, Nb and V in total; 0 to 0.01% of P, Mg in total; 0 to 0.0075% of S; 0 to 0.30% of Pt; 0 to 0.10% of Re; 0 to 0.15% of Pd; 0 to 200 ppm of N2; and 0 to 200 ppm of O; Ni making up the balance of the composition; the combined amount of W and Re not exceeding 7.4% and the combined amount of W and Mo being at least 8.5%, given that the percentages mentioned above are given in relation to the total of the rest of the powder.An alloy that can be produced from this powder and a process for producing this alloy from this powder are also proposed.
