Explain	Characteristics and use:GH2132 superalloy is a Fe-25Ni-15Cr base superalloy, which is comprehensively strengthened by adding molybdenum, titanium, aluminum, vanadium and trace boron. It has high yield strength, endurance and creep strength below 650 ℃, and good processing plasticity and satisfactory welding performance. It is suitable for manufacturing high-temperature load-bearing parts of aero-engine that work under 650 ℃ for a long time, such as turbine discs, press discs, rotor blades and fasteners. ① Processing performance: The high alloying degree and poor thermal conductivity of superalloy lead to high cutting temperature, high cutting force and severe work hardening, especially the high hardness of alloy, serious tool wear and high cutting cost. At present, cemented carbide tools are basically used for machining, and centerless grinding is used for those with high requirements for dimensional progress and roughness. At present, most of the alloy bolts and screws are formed by hot upsetting, and a few are formed by cold upsetting. Because cutting will cut off the metal flow line under the head of the product and cause great damage to the strength of the joint between the head and the rod, all bolts and screws are upset with round bar or wire. ② Heat treatment performance GH2132 is generally used in the solution aging state, with tensile strength up to 1300MPa and hardness up to 40HRC. The microstructure of the alloy in the solution state is γ After aging, the microstructure of austenitic matrix is γ Spherical Ni3 type uniformly distributed on austenite matrix γ\\\\\\\' There is a small amount of M3B2 boride in the phase, TiN, TiC and grain boundary, and there may be a small amount near the grain boundary η Phase and L phase (these two phases are harmful). and γ\\\\\\\' Phase is the alloy strengthening phase, which strengthens the alloy by blocking the movement of dislocation. There is a small amount of M3B2 in the grain boundary, which can significantly improve the grain boundary strength of the alloy, thus improving the high-temperature mechanical properties of the alloy. ③ Selection suggestions: GH2123 superalloy is widely used in products with high temperature resistance and oxidation resistance requirements, and can be used to produce various kinds of bolts, screws, self-locking nuts and other products including navigation aids HB, GB, GJB. The head of the product is mostly formed by hot upsetting, and the wire rolling or rolling is after the final heat treatment (aging). It is recommended to use in the environment where the tensile strength is in the range of 900~1300MPa, the hardness is in the range of 25~40HRC, and the long-term operation is below 650 ° C, and the oxidation resistance is required.
