This program was concluted to develop the technology necessary to establish a cost effective approach to the production of titanium alloy parts for both aircraft engine and airframe applications. This approach was based on a PM near-nte shape process utilizing ceramic mold techniques in conjunction with HIP (Hot Isostatic Pressing) to a minimum machining envelope. Program objectives included: the optimization of an exsting PM process for the HIP of near-net shapes of titanium using low-cost tooling; the reduction of the process to an efficient, cost effective, manufacturing procedure; and thorough characterization of the end product. In cooperation with General Electric (GE) and McDonnell-Douglas (MCAIR) as subcontractors, representative components and alloys were selected for this program. These were a Ti-17 compressor stub shaft and a Ti-6-4 keel splice former. Hot Isostatic Pressing parameters were optimized for both the Ti-17 and Ti-6-4 alloy using the ceramic mold process. SiO2 was chosen as the most promising mold material. The ability to produce near-net shapes of both engine and airframe components was sussessfully demonstrated. (DePo)
