GH2136 (GH136) Mechanical Properties Tensile strength σb (MPa): ≥950 Conditions yield strength σ0.2 (MPa): 700 Elongation δ5 (%): ≥15.0 section shrinkage ψ (%): ≥20 4 . GH2136 (GH136) Key Features: GH2136 (GH136) 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, On the solid solution matrix-forming compound may be a strengthening phase, so commonly used in the form of a solid solution heat treatment and aging treatment. By solution treatment, the GH2136 (GH136) 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.GH2136 (GH136) Application examples: GH2136 (GH136) for the manufacture of turbine disk material of 650 ~ 700 ℃.
