Abstract
We had two national projects in which superalloys were developed. The first one was “Advanced Gas Turbine”; in this project we treated conventionally cast nickel-base superalloys and directionally solidified nickel-base superalloys. Those alloy developments started in 1978 and ended in 1984. The second one, 1981 to 1988(fiscal), was “Advanced Alloys with Controlled Crystalline Structures”; single crystal nickel-base superalloys, superplastically workable nickel-base P/M alloys, and oxide dispersion strengthened nickel-base superalloys were treated. This paper briefly reviews the alloy developmental studies and process studies carried out in the two projects.
