CHRYSLER’S GAS TURBINE CAR - Materials Requirements

Both conventional and newly developed materials used in unique applications have played an important role in making the Chrysler gas turbine engine a practical powerplant. The new low-cost materials developed by Chrysler Metallurgical Research include, (a) a series of iron-base super alloys having equivalent or superior life to aircraft type alloys, (b) heat resisting iron aluminum alloys for elevated temperature service under low stress application, and (c) long life rubbing seal materials that operate satisfactorily from ambient temperature up to 1200°F and above.

These materials appear to meet all present or immediate high temperature alloy requirements for a competitive mass produced automotive turbine.
