A first embodiment of a nickel based alloy consists essentially of from 3.0 to 5.2 wt% chromium, from 1.5 to 3.0 wt% molybdenum, from 6.0 to 12.5 wt% tungsten, from 5.0 to 11 wt% tantalum, from 5.5 to 6.5 wt% aluminum, from 11 to 14 wt% cobalt, from 0.001 to 1.75 wt% rhenium, from 0.2 to 0.6 wt% hafnium, up to 0.05 wt% yttrium, up to 3.0 wt% ruthenium, and the balance nickel. Another embodiment of a nickel based alloy consists essentially of from 1.0 to 3.0 wt% chromium, up to 2.5 wt% molybdenum, from 11 to 16 wt% tungsten, from 4.0 to 8.0 tantalum, from 5.7 to 6.5 wt% aluminum, from 11 to 15 wt% cobalt, from 2.0 to 4.0 wt% rhenium, from 0.2 to 0.6 wt% hafnium, up to 0.05 wt% yttrium, up to 3.0 wt% ruthenium, and the balance nickel. |
