Abstract
Turbine engine alloys modified by the addition of small amounts of gold are found to have improved properties over similar alloys that do not contain Au. These improved alloys have special application in gas turbines and jet engines. Preferred composition ranges are (36 to 45) wt % Ni-(25 to 32) wt % Fe-(16 to 21) wt % Cr-(0.3 to 0.4) wt % Al-(0.3 to 0.4) wt % Ti-(0.6 to 0.8) wt % Mn-(0.3 to 0.4) wt % Cu-(0.02 to 0.05) wt % C-(0.02 to 20) wt % Au and (44 to 56) wt % Fe-(20 to 26) wt % Ni-(12 to 16) wt % Cr-(1 to 1.3) wt % Mo-(1.7 to 2.2) wt % Ti-(0.2 to 0.3) wt % V-(0.15 to 0.21) wt % Al-(0.001 to 0.003) wt % B-(0.15 to 0.21) wt % Mn-(0.3 to 0.7) wt % Si-(0.02 to 0.05) wt % C-(0.02 to 20) wt % Au.
