Abstract：Powder superalloy is a key material for manufacturing rotating components that high-performance aero-engine turbine discs. Segregation of components is limited into the powder particles， which can eliminate the macroscopic segregation of conventional casting and has the advantages of uniform microstructure and fine grains， obtaining good yield strength and fatigue properties. The development， preparation methods and consolidation process of powder superalloy were summarized. In addition， the main defects existing in powder superalloy were described. The development status of laser additive manufacturing technology was also summarized， and the research progress of numerical simulation of powder superalloys was briefly demonstrated. Finally， according to the domestic demand situation of powder superalloy， the development direction of powder superalloy in the future was predicted.
