Improvements in materials have been critical to advances in the propulsion system. Over the past 50 years, many improvements have been made to nickel-based superalloys to satisfy design requirements; several key developments will be highlighted. Today, millions of pounds of super- alloys are annually produced for use in turbine blades, vanes, disks, cases, and frames through- out the engine. Looking to the future, several themes emerge, although predicting the future is inherently risky.
