Gamma Titanium Aluminides

This class of alloys with high-temperature oxidation resistance and improved specific properties at elevated temperatures holds the potential to replace certain nickel-based super-alloy components in aircraft engines.

For example, they allow the manufacture of low pressure turbine blades at half the weight of conventional super-alloy components. Lighter, cleaner, and more fuel efficient engines produced with gamma aluminides increase the performance potential of next-generation aircraft.
