Abstract:Superalloys, serving as the critical materials for hot-end components like turbine blades, combustion chambers, and turbine disks, are widely used in aviation, aerospace, and energy sectors due to their excellent performance in high-temperature environments. However, controlling the microstructure of superalloys remains a significant challenge in actual production. Radial forging, with its high efficiency, high material utilization, and significant improvement of the microstructure of forgings, shows great potential in the production of superalloy materials. Through multiple hammers and high-frequency forging, radial forging achieves uniform deformation of the billets, enhancing the mechanical properties and internal density of the forgings. This paper systematically elaborates on the driving principles of radial forging equipment and the influence of key process parameters on the production process. It analyzes the microstructure evolution mechanism and grain growth behavior of superalloys under multi-pass high-frequency forging, compares the applicability of different forging penetration models, and summarizes the current research status of stress-strain constitutive models and microstructure evolution models in finite element simulation. This review also points out that high-precision multi-physics coupled simulation and intelligent process design are the core directions for future development.
