摘要
Equiaxed grain cast superalloys are widely used in aeroengine and other fields due to their low manufacturing cost and excellent mechanical properties at medium and low temperatures. Aeroengine casing is a typical complex thin-walled equiaxed superalloy castings used at medium and low temperatures. The complex thin-walled superalloy investment castings with the complex structures, the accurate size and the lightweight are the key components for advanced aeroengines. The coordinated control of the precise forming and the solidification microstructure for these castings is very difficult. Correspondingly, the requirements for materials, casting technologies, structure controls and mechanical properties in superalloy integral structure castings are becoming increasingly higher. In this paper, the development and application of polycrystalline superalloys, solidification and forming, the simulations and the new technologies are reviewed.
