    Abstract:

    Superalloy exhibits excellent overall performance at high temperature. As a result, it is widely used in the field of aerospace, petrochemical engineering and so on. Superalloy ring forging is mainly used in the component of receiver, combustor, sealing ring, et al. With the development of high performance aero-engine, the demand of superalloy ring forging with high quality keeps increasing. Previously, most focus is put on superalloy used for turbine disks and blades. Related research is carried out on alloy design and optimization, manufacture technology and deformation mechanism. However, there is only limited work about superalloy ring forging. Hence, in this work, the development of ring rolling technology of superalloy ring forging is summarized. The application of numerical simulation technique in manufacture process design of superalloy ring forging is discussed. The main superalloy used as ring forging is compared. At last, the difficulty in microstructure control during ring rolling process of superalloy analyzed. This review work is made hoping to provide some theoretical guidance for the research and development of superalloy ring forging with high quality.
