Abstract：As a key material for turbine disks, powder metallurgy (PM) superalloys are developing in the direction of higher performance. However, there are still some urgent key problems in the preparation process of the alloys, which restrict the further development and application. This paper outlines the progress of PM superalloys from three aspects: the development history, the composition, and the preparation process, analyzes the causes and corresponding solutions to the problems of difficult removal of inclusions, easy to crack, and high cost in the alloys, summarizes the current status of the research on PM superalloys, and looks forward to the future development trend of the alloys.
