Nickel-based heat-resistant alloys have been widely used in the manufacture of high-temperature parts such as turbine blades, guide vanes, engine valves and turbine discs due to their excellent resistance to high temperature creep. The research on this alloy has developed rapidly in recent years. This paper summarizes the research status and development of the nickel-based heat resistant alloys related to hot deformation behavior. Based on the macroscopic thermal deformation behavior of the alloy, the paper introduces three models and two types of processing maps that the researchers often use to construct the constitutive model of the material. For the research status of microstructure evolution of the nickel-base heatresistant alloy during thermal deformation, this paper summarizes the research status of the objective function method in nickel-based alloys, and introduces the application of grain boundary engineering regulation in nickel-based heat-resistant alloys.
