GH141 precipitation-reinforced nickel-based alloy

GH141 is a precipitation-hardening nickel-based deformed high-temperature alloy with high tensile and enduring creep strength and good oxidation resistance in the 650-900°C range. Due to the high content of aluminum, titanium and aluminum in the alloy, it is difficult to open ingots, but the deformed material has good plasticity and can be cold formed in the annealed state or welded, and the welded parts are susceptible to strain aging cracks during heat treatment. GH141 Alloy varieties are thin plates, strips, wires, discs, rings, forgings, rods and precision castings, suitable for manufacturing at 870 ℃ below the requirements of high strength and 980 ℃ below the requirements of high-temperature parts of aviation and aerospace engines oxidation.

GH141 is a Ni-Cr-Co based precipitation hardening deformed high temperature alloy with long term use temperature up to 980 degrees C. It has high tensile, tensile and creep strength, yield and fatigue resistance and good oxidation resistance in use temperature 650-900 degrees C. It is one of the plate alloys with high mechanical properties in use below 980 degrees C. It has good machinability and is used for making parts requiring high strength below 870 degrees C and oxidation resistance below 980 degrees C. The alloy has good machinability and is used to make parts requiring high strength below 870 degrees C and oxidation resistance below 980 degrees C. Welding properties. GH141 is used to make engine combustion chamber inner sleeves, high pressure turbine outer ring support and retaining rings, high pressure guide outer and support rings and fasteners. Due to the high content of aluminum, titanium and molybdenum elements in this alloy, it is difficult to open the embryo forging, but the plasticity is good after opening the embryo. GH141 alloy can be fusion welded, diffusion welded, brazed and friction welded. The fusion welding can be done by electron beam welding and argon arc welding. Before welding, solid solution treatment or over-aging treatment is required to eliminate the tendency of strain aging cracks in the weld. Cutting processing without special requirements
