Abstract
A heat-resistant alloy consists of Cr 5-20 per cent, Al 0.5-5 per cent, Ti 0.5-3 per cent, Mo 0.5-10 per cent, B 0.0003-0.009 per cent, C 0.01-0.25 per cent, Zr 0.01-0.25 per cent, Fe 0-5 per cent, Mn 0-4 per cent, Si 0-2 per cent, Cu 0-2 per cent, Mg 0-0.1 per cent, Ni balance except for impurities and residual dioxidizers, the matrix hardening factor (Cr+ 2 Mo+Fe) being from 8 to 27. The alloy may be heated at 1800-2200 DEG F. for 1/4 -8 hours, air cooled or quenched and heated at 1200-1600 DEG F. for at least 1 hour. Impurities referred to comprise V, Ce, Pb, Bi, Te, S, Se, As, Sb, W, Nb and Co. The precipitation hardening factor (Al+Ti) is preferably 3.5 to 5. In an example, Ni and Cr are melted in an induction furnace and Mo added to the melt; C is then added as a 10-90 C-Cr master alloy; half the Al is then added, followed by Mg and Zr; the balance of the Al is then added, followed by Ti and finally B. The alloys may be used for the blades of gas turbines and other parts of jet engines.
