Recently, with the development of aviation engines and ground-based gas turbines, the demands for the environmental resistance and temperature-bearing capacity of their key hot-end components have considerably increased. Compared to Ni-based superalloys, novel γ′-strengthened Co-based superalloys are more advantageous owing to their corrosion resistance and melting temperature. To facilitate the development of these alloys, research on their alloying principles, alloy design, and creep mechanisms is summarized in this paper based on domestic and international results. Furthermore, herein, the key scientific problems in the development of such alloys are discussed, and the possible development trends and challenges in the future are surveyed.
