This program addresses the development of iron aluminide base alloys by rapid solidification and the determination of their potential for use in aircraft turbine engines as alternatives to high chromium steels and nickel-base alloys. The program was divided into three tasks. A process and model development task to define thermomechanical processing requirements for Fe3A1 base alloys, a task to produce and deliver to the Air Force Materials Laboratory a number of alloys produced by the PW rapidly solidified powder process and a task for the development of austenitic Fe-Mn-A1 alloys with improved elevated temperature properties.
