Explain	GH2901 is a Fe-Ni-Cr base precipitation hardening deformation superalloy. Metastable γ＇ [Ni3 (Ti, Al)] phase is aging strengthened, and a small amount of aluminum is inhibited γ＇ towards η- Transformation of Ni3Ti phase. The alloy has high yield strength and rupture strength below 650 ℃, good oxidation resistance below 760 ℃, and stable structure after long-term use. The main products include turbine disk, compressor disk, journal, static structural parts, turbine outer ring and fasteners. GH2901 alloy has no notch sensitivity after standard heat treatment and long-term aging at 550 ℃~750 ℃. However, when forging, if the process parameters are not properly selected or operated, the long strip or lamellar harmful phase TizSC and large granular boride and Ti (CN) phase can be precipitated at the grain boundary after standard heat treatment, resulting in notch sensitivity during the endurance test. At this time, it is impossible to eliminate notch sensitivity through heat treatment, but only through re-hot processing deformation can obtain appropriate structure, and the expansion coefficient of the alloy is close to that of ferritic heat strength alloy steel, The two materials can be connected without special provisions for thermal expansion. GH2901 alloy has been used to make rotating parts and fasteners of aero-engine and ground gas turbine, and the service life of alloy parts is longer;
