GH4037 (GH37) alloy is an austenitic aging-strengthened nickel-based alloy. Approximately 4% of aluminum and titanium are added to form a γ phase for aging strengthening, and more tungsten and molybdenum are added for solid solution strengthening, and a small amount of tungsten and molybdenum are added for solid solution strengthening. Boron strengthens the grain boundaries. The alloy is used below 850°C, has high thermal strength, good overall performance and structural stability, and is widely used in the manufacture of aero-engine turbine working blades, and is used for a long time below 800-850°C.
