Abstract:
PM superalloy is key structural materials applied for turbine disc of high thrustweight ratio aeroengine. PM superalloy development in America and Russia is mainly summarized. According to manufacturing process of PM superalloy, different process routes including powder atomization, powder consolidation and disc forming are compared, defects and corresponding controlling methods in PM superalloy are analyzed. The domestic development of PM superalloy is also summarized. PM superalloy applied for aeroengine is summarized. According to developing trend of PM superalloy, the key technologies such as ultra fine and clean powder atomization, near net shape forming by HIP, dual microstructure heat treatment(DHMT) are prospected in developing highperformance PM superalloy. According to current development condition of PM superalloy in china, existed problems and corresponding developing direction are pointed out. 
