The Nimonic 263 alloy is advanced supercritical unit with candidate material, has the organization stability, deformation of cobalt nickel base super alloy is aging aggrandizement, contains a high amount of cobalt and a variety of reinforcement element, the alloy in 815 ~ 815 ℃ has higher tensile strength and creep resistance, good resistance to oxidation and corrosion resistance, in cold and hot alternate again and again under the action of alternating have high fatigue strength and good formability and weldability. Used for turbine engine turbine disc, blade, high temperature fastener, clamp, sealing ring and elastic element etc.
The 263 alloy was precipitated and hardened, and a nickel-chrome-cobalt alloy was added for solid solution strengthening.263 alloys not only have high strength and corrosion resistance, but also show good formability and high temperature ductility in the welding structure.
Nimonic 263 Alloy is easy to produce internal crack in forging, allowing heavy hammer blow. Ingot furnace temperature is not higher than 700 ℃, low temperature area to preheat the first 20-30 minutes, finally the heating temperature of 1150 ℃ to 1180 ℃, open forging temperature is not lower than 1050 ℃, the final forging temperature is not lower than 950 ℃.
The average grain size of the alloy is closely related to the deformation degree and final forging temperature of the forging.
