Nickel-based alloys refer to a class of alloys that have comprehensive properties such as high strength and certain oxidation and corrosion resistance at high temperatures of 650 to 1000 °C. According to the main properties, it is subdivided into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys and nickel-based shape memory alloys. According to the different substrates, superalloys are divided into: iron-based superalloys, nickel-based superalloys and cobalt-based superalloys. Among them, nickel-based superalloys are referred to as nickel-based alloys.
