Description

technical field [0001] The invention relates to an alloy material, in particular to a preparation method of a nickel-based high temperature resistant alloy material. Background technique [0002] Nickel-based superalloys are the most widely used superalloys with the highest high-temperature strength. They are mainly used in the manufacture of high-temperature turbine blades, guide vanes, turbine disks, high-pressure compressor disks, and combustion chambers for aviation, naval and industrial gas turbines. It is also used in the manufacture of energy conversion devices such as aerospace vehicles, rocket engines, nuclear reactors, petrochemical equipment, and coal conversion. Nickel-based alloys are the most widely used superalloys with the highest high-temperature strength. Nickel-based superalloys have excellent resistance to high-temperature oxidation and high-temperature corrosion. Compared with iron-based superalloys, nickel-based superalloys have good thermal conductivi...

Problems solved by technology

So far, although nickel-based alloy technology has been greatly developed, there are still many problems, such as wear resistance, hardness, rust resistance, corrosion resistance, high and low temperature resistance, brittleness, toughness, and cost. In many occasions, it still cannot meet the production requirements, and further improvement is needed to improve production efficiency, reduce costs, improve safety, provide guarantee for the development of high-tech, and provide impetus for social development. The task is still very arduous.
