摘要
A low density nickel based superalloy having good creep characteristics when hot, and intended in particular for making turbomachine parts by monocrystalline solidification, wherein the composition of the alloy in percentages by weight is as follows: -Co: 5% to 7% Cr: 5% to 10% Mo: 0.5% to 2.5% -W: 3% to 5% Al: 6% to 7.5% Ti: 1.5% to 2.25% -Nb: 0% to 0.5% Ta: 2% to 4% V: 0.3% to 0.6% -Ni: balance to- 100%. - Parts, e.g. turbomachine blades, made from the alloy.
