Abstract:

P/M superalloy is the preferred materials of critical advanced aero-engine hot section, advanced powder preparation technique is the key technologies to obtain high-quality superalloy powder and to ensure the quality of P/M superalloy. In recent years, breakthrough progress has been made on China’s research and production of P/M superalloy. The new generation P/M superalloy were successfully developed and the mature process were formed on production of P/M superalloy. The pure powder preparation technology has been developed to meet the requirements of aero-engine P/M superalloy key parts，through the in-depth research on high-purity master alloy smelting technology, advanced atomization technology and electric separation technology. This paper briefly reviews the domestic and international development of P/M superalloy. The source and their impact of defects in P/M superalloy were analyzed. Then, three key technologies of superalloy powder production process were summarized. At last, the further development direction of superalloy powder preparation technology were discussed in this paper.
