Abstract Ni-based superalloy components with thin-walled are the core parts of high-end equipment. Spinning is the most effective method to manufacture these parts with high accuracy and excellent performance. The spinning technology of Ni-based superalloy was comprehensive discussed by analyzing the spinnability, macro-forming quality, microstructural evolution and shape/property integrated control. The influences of initial microstructure of the blank and the forming temperature on the spinnability during flow forming process were analyzed. The influences of the process parameters on macro-forming quality of spun parts were summarized. The microstructural evolution mechanisms during flow forming at room temperature and hot flow forming were discussed. The integrated control method of shape/property of spun parts during hot flow forming was explored.
