<p>The invention relates to a nickel alloy derived from René 125, but with reduced levels of certain elements (Zr, B, P, S, Si and, to a lesser extent, Ti and Hf) in order to limit the appearance of cracks upon solidification in a moulding process. Specifically, 4.80%≰Al≰5.00%, 1.48%≰Hf≰1.52%, 2.28%≰Ti≰2.33%, 0.005%≰B≰0.01%, 1.77%≰Mo≰1.97%, and Zr≰0.007%. Other elements can have levels that match those of René 125.</p> |
