Nickel-based superalloy is an essential material to prepare hot-end components in aero-engines and gas turbines,due to its excellent mechanical properties under high temperature. Additive manufacturing(AM) is one of the most important techniques to fabricate superalloy components with complex geometry. In this paper,the research progress of microstructure and defects of AMed superalloy is reviewed. Based on the existing literature,tensile properties of GH3536,GH3625 and GH4169 are summarized. Typical applications of AMed superalloy components in aero-engines and gas turbines are presented. Finally,for the problems in existing investigations,it is suggested that the future research can focus on materials design,heat treatment/hot isostatic pressure process optimization,single crystal preparation,real-time monitoring technique development and internal surface treatment technique innovation.
