Abstract: | P/M superalloy is the preferred material for critical hot sections of advanced aero-engine, advanced powder preparation technique is the key to obtain high-quality superalloy powder and ensure the quality of P/M superalloy. In recent years, breakthrough has been made on research and production of P/M snperalloy in China, the new generation P/M superalloy was successfully developed and the mature production process of P/M superalloy was formed. The pure powder preparation technology has been developed, which meets the requirements of P/M superalloy aero-engine key parts, through the in-depth research on high-purity master alloy smelting technology, advanced atomization technology and electric separation technology. This paper briefly reviewed the domestic and international development of P/M superalloy. The sources of defects in P/M superalloy and their impact on the property of the alloy were analyzed. Then, three key technol- ogies of superalloy powder production process were summarized. Lastly, the further development direction of superalloy powder preparation technology was discussed. |
