GH2130 (GH130) mechanical properties: Test temperature 800 ℃: Conditions yield of: σ0.2 (MPa): ≥600, tensile strength σb (MPa): ≥850, elongation δ5 (%): ≥15, section shrinkage ψ (%): ≥20 4. GH2130 (GH130) Key Features: GH2130 (GH130) is our own successful research Fe - aging strengthening nickel-base alloys, nickel-based alloys used in place of GH4037. GH2130 (GH130) alloy with high heat resistance and good processing plasticity, fatigue properties, notch sensitivity worse than GH4037. In order to improve the oxidation resistance, it can be surface aluminized or other measures. GH2130 (GH130) alloy of chromium and nickel content is relatively low, so the anti-oxidation temperature is only about 800%, but with dispersion strengthening phase forming elements (v, A1, Ti) is relatively high, the solid solution strengthening the matrix may be formed compound phase, so commonly used in the form of a solid solution heat treatment and aging treatment. By solution treatment, the GH2130 (GH130) solid solution strengthening alloy; aging treatment, can strengthen the alloy phase precipitation of fine [VC, Ni3A1, Ni3Ti, Ni3 (A1 Ti?)], Thereby increasing temperature and high temperature strength. Organization after solution and aging treatment of austenite + diffusion compound. 5.GH2130 (GH130) Application examples: GH2130 (GH130) applies to below 800 ℃ turbo and gas turbine blade materials.
