Summary

A wrought nickel-base superalloy based on the Ni-Cr-W system was developed for high-temperature applications. The new alloy is solid solution and carbide strengthened. It is essentially free of cobalt, and it resists the formation of detrimental intermetallic compounds after prolonged exposure to elevated temperatures. Various mechanical, oxidation and physical properties of the new alloy were measured, and the microstructural features were characterized. These were compared with those of other solid solution-strengthened superalloys. Also, the fabricability of the alloy was evaluated. A number of advantages of the new alloy are defined.
