Superalloys
Superalloys are a class of high-performance alloys that exhibit excellent mechanical strength, resistance to thermal creep deformation, good surface stability, and corrosion resistance at high temperatures. These alloys are primarily used in extreme environments such as gas turbine engines, rocket engines, nuclear reactors, and other high-temperature applications in the aerospace and astronautical industries. Superalloys are typically composed of a base metal, such as nickel, cobalt, or iron, along with various alloying elements such as chromium, tungsten, molybdenum, and others. The unique properties of superalloys are due to the formation of a protective oxide layer on the surface of the material, which provides excellent resistance to high-temperature oxidation and corrosion. The development of new superalloys with improved properties is an ongoing area of research in the field of materials science and engineering.
