<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> |
