Aero-engine is the core of modern aviation industry, and its performance directly affects the speed, maneuverability and range of aircraft. In order to meet the needs of turbine blades under extreme operating conditions, especially high temperature and pressure environments, nickel-based superalloys have been rapidly developed since the late 1930s. In this paper, we will review the development of nickel-based superalloys from Nimonic series to directional solidification and single crystal superalloys, discuss how these materials can gradually improve the temperature resistance and mechanical properties of turbine blades, promote the continuous improvement of aero engine performance, and look into the future development trend.<\/p>

In order to meet the needs of hot-end components for turbojet engines, nickel-based superalloys have been developed since the late 1930s. In 1939, the British Mond Nickel company developed Nimonic75 alloy, and then developed Nimonic80 alloy by adding Al and Ti elements. In 1942, Nimonic80 was successfully used in turbin b\u0131\u00e7a\u011f\u0131<\/a> materials, which was the first application of \u03b3’-Ni3(Al, Ti) phase reinforced materials. After that, a series of alloys such as Nimonic80A, Nimonic90, Nimonic95, Nimonic100 and Nimonic115 were formed by adding B, Zr, Co and other elements to further improve the alloy properties. The development path of superalloys in the United States and the former Soviet Union is similar to that in the United Kingdom.<\/p>

In the mid-1940s, Halliwell developed K42B alloy for the manufacture of piston aero engines. Subsequently, PW Company, CE company and special metals company developed Waspalloy, M252 and Udimet500 alloys respectively in the 1950s, and on this basis formed Inconel, Mar-M and Udimet series alloys. These alloys are made into parts such as turbine blades by forging, rolling and other processes, and are called deformation superalloys. However, with the development of the aviation industry, the blades need to withstand higher working temperatures and strengths, as well as the increase in structural complexity, resulting in deformation superalloys that cannot meet the demand, which gave birth to casting superalloys.<\/p>
