Abstract
Platinum-modified nickel-based superalloys and turbine engine components are provided. The platinum-modified nickel-based superalloy includes, by weight, aluminum, in a range of about 7.8 percent to about 8.2 percent, tantalum, in a range of about 5.0 percent to about 6.0 percent, rhenium, in a range of about 1.6 percent to about 2.0 percent, platinum, in a range of about 0.8 percent to about 1.4 percent, hafnium, in a range of about 0.20 percent to about 0.40 percent, silicon, in a range of about 0.30 percent to about 0.60 percent, about 0.02 percent carbon, about 0.01 percent boron, and a balance of nickel. The platinum-modified a nickel-based superalloy may also include, by weight, chromium in a range of about 4.0 percent to about 5.0 percent.
