The nickel-based alloy was developed in the late 1930s. The nickel-based alloy Nimonic 75 was first produced in the United Kingdom in 1941. In order to increase the creep strength, Al was added and Nimonic 80 was developed.

The United States in the mid-1940s, Russia in the late 1940s, and China in the mid-1950s also successively developed nickel-based alloys. The development of nickel-based alloys includes two aspects, namely the improvement of alloy composition and the innovation of production technology.

In the early 1950s, the development of vacuum smelting technology created conditions for refining nickel-based alloys with high Al and Ti content and drove a substantial increase in alloy strength and service temperature. In the late 1950s, due to the increase in the working temperature of turbine blades, alloys were required to have higher high-temperature strength, but when the strength of the alloy was high, it was difficult to deform, or even unable to deform. Therefore, precision casting technology was used to develop a series of good high-temperature strengths. Of casting alloys. In the mid-1960s, directional crystalline and single crystal superalloys with better performance were developed, as well as powder metallurgy superalloys.

In order to meet the needs of ships and industrial gas turbines, a number of high-Cr nickel-based alloys with good thermal corrosion resistance and stable structure have been developed since the 1960s. In about 40 years from the early 1940s to the late 1970s, the working temperature of nickel-based alloys increased from 700 to 1,100°C, an average annual increase of about 10°C.
