Ni-based superalloys are a class of high-performance materials that are primarily composed of nickel, along with other elements such as chromium, cobalt, and aluminum. These alloys are known for their excellent mechanical properties, high temperature strength, and resistance to corrosion and oxidation. They are widely used in industries such as aerospace, gas turbine engines, and nuclear power generation, where high temperature and corrosive environments are common. Research in the field of Ni-based superalloys focuses on improving their properties in order to meet the increasing demands for more efficient and reliable materials. This includes developing new alloy compositions, optimizing processing techniques, and understanding the underlying mechanisms that govern their microstructure and properties. Overall, research in this area aims to push the limits of what is possible with these materials and expand their applications in various industries.
