Nickel-based superalloys refer to high-temperature alloys with high strength and good resistance to oxidation and gas corrosion in the range of 650-1000 ° C with nickel as the matrix (generally greater than 50%). Nickel-based superalloys (hereinafter referred to as nickel-based alloys) were developed in the late 1930s. In 1941, the United Kingdom first produced the Ni-based alloy Nimonic 75 (Ni-20Cr-0.4Ti); in order to increase the creep strength and added aluminum, Nimonic 80 (Ni-20Cr-2.5Ti-1.3Al) was developed. In the mid-1940s, the Soviet Union in the late 1940s, China also developed nickel-based alloys in the mid-1950s.
