Description

technical field [0001] The invention belongs to the technical field of nickel-based superalloys, and in particular relates to a high-performance nickel-based superalloy and a manufacturing method thereof. Especially for high-performance nickel-based superalloys strengthened by γ' phase and carbide. Background technique [0002] Inconel713C alloy is a γ'-phase precipitation-strengthened nickel-based cast superalloy. The weight percentage of the alloy chemical composition is (Wt-%): C: 0.08-0.20, Cr: 12.0-14.0, Mo: 3.8-5.2, Nb: 1.8-2.8 , Al: 5.5-6.5, Ti: 0.5-1.0, B: 0.005-0.015, Zr: 0.05-0.15, Si≤0.5, Mn≤0.25, Cu≤0.5, Fe≤2.5, Co≤1.0, Ni: balance. The alloy has the advantages of high creep strength below 980°C, long-term structural stability, hot corrosion resistance and thermal fatigue characteristics, and good casting process performance. At present, it has been widely used in various industrial fields, especially aerospace, shipbuilding, automobile, petrochemical and so on...
