COSAM program overview
Abstract
The COSAM program for reduction of the use of strategic alloying elements in nickel-based superalloys for gas turbine engines was reviewed. Sources, consumption, and pricing of cobalt, tantalum, columbium, and chromium are surveyed. Research projects in strategic element substitution, advanced processing concepts, and the development of alternate materials (intermetallics and iron-base alloys) are listed and research plans for FY 1983 and FY 1984 summarized.
