Description
technical field [0001] The invention relates to the field of alloy technology, in particular to a nickel-based superalloy for an exhaust valve. Background technique [0002] Superalloys are alloys based on Group VIIIA metals (iron, cobalt, nickel) with high room temperature and high temperature strength. It has been more than 60 years since the generation and development of superalloys. Driving its development is the demand for heat-resistant alloys for gas turbines in the aerospace industry. The development of superalloys has also led to the progress of alloychemistry and alloy processing technology. Nickel-based superalloys have higher high-temperature strength. They are developed on the basis of Cr20Ni80 alloys, and are usually strengthened with alloy elements such as Cr, Mo, Co, Ti, Al; the main elements of Cr, Mo, Co, etc. The function is to strengthen the nickel-based solid solution, increase the recrystallization temperature of the matrix, and reduce the diffusion...
