【摘要】 回顾了８０年代初以来我国粉末高温合金的研制过程和取得的阶段性成就。着重介绍了ＦＧＨ９５合金生产中所采用的等离子旋转电极制粉及筛分、静电处理工艺，热等静压＋包套锻造成形工艺，以及生产过程中粉末及制件的质量控制。此外还介绍了ＦＧＨ９５合金制件的组织性能和热处理工艺。通过近２０年的探索，采用上述工艺，并以自制的整套粉末高温合金生产设备，成功地试制和生产了以涡轮盘件、涡轮档板为主的粉末合金制件。文章最后指出我国粉末高温合金下一步的研究方向。更多还原

【Abstract】 This thesis views in retrospect the development and stage achievement of PM superalloys in China since early 80’s. It mainly introduces the PREP,sieve processing,static eletricity separating processing,HIP+case forging processing,and the quality control of powders and parts of PM FGH95. It also presents the microstructure,properties and heat treatment of FGH95 alloy parts. After nearly twenty years perspiration,we can successfully use a set of PM superalloys producing equipment and the above technics to ma nufacture PM superalloy parts including turbine disks and turbine rings. It also presents the further research on PM superalloys in China.更多还原
