Abstract:

The primary payoff in selection of wroughtcast alloys containing strategic elements is performance, not cost. For example, in commercial engines, the temperatures that parts are exposed to have increased steadily in an effort to improve specific fuel consumption. In military engines, higher operating temperatures are usually governed by efforts to improve thrust to weight ratio. This paper will review the trade-offs that a designer must make in the selection of materials for specific component applications. Emphasis will be placed on discussion of what options are available in reducing the strategic material content of the engine system while still achieving performance and cost objectives. Author
