Abstract
Nickel-based superalloys, turbine blades, and methods of improving or repairing turbine engine components are included. A nickel-based superalloy includes, by weight, about 5% to about 12% cobalt, about 3% to about 10% chromium, about 5.5% to about 6.3% aluminum, about 5% to about 10% tantalum, about 3% to about 10% rhenium, about 2% to about 5% of one or more of elements selected from a group consisting of platinum, ruthenium, palladium, and iridium, about 0.1% to about 1.0% hafnium, about 0.01% to about 0.4% yttrium, about 0.01% to about 0.15% silicon, and a balance of nickel.

A single crystal turbine blade comprising:
- a nickel-based superalloy including:
- about 7% to about 12% cobalt, by weight;
- about 3% to about 10% chromium, by weight;
- about 5.5% to about 6.3% aluminum, by weight;
- about 5% to about 10% tantalum, by weight;
- about 3% to about 10% rhenium, by weight;
- about 2% to about 5% of one or more of elements selected from a group consisting of palladium and iridium, by weight;
