Abstract

Abstract In this paper, the research and application of nickel base superalloy GH4169 in recent years was introduced. GH4169 alloy is a precipitation strengthened nickel base superalloy, which has been widely used in aeroengine, petroleum, nuclear industry and other fields. The phase composition, three common heat treatments as well as the application prospect were elaborated. At last, the service temperature range and application area of GH4169 alloy was believed to be further expanded with the adjusted alloy composition and the corresponding hot working process.
