ABSTRACT:
The addition of small amounts of rhenium, technitium and their mixtures and, optionally erbium, to a nickel based superalloy consisting essentially of 19.3-19.7 weight percent chromium, about 0.5% carbon, about 2.5% iron, the balance essentially nickel, provides enhanced mechanical properties particularly suitable for applications in gas turbine engine components.
