介绍了国内外粉末高温合金的发展应用状况、国外粉末研究的新的进展，并总结分析了涡轮粉末高温合金的研究成果和发展方向。前言 涡轮盘是发动机重要的热端部件之一，它在极为苛刻的条件下工作，飞行时承受着启动一停车循环中的机械应力和温差引起的热应力的叠加作用，因而要求
The development and application status of powdery superalloys at home and abroad, the new progress of foreign powder research, and the research results and development direction of turbine powder superalloy are summarized. INTRODUCTION Turbine discs are one of the most important hot end components of engines. They operate under extremely harsh conditions and suffer from the superposition of mechanical stresses and thermal stresses in starting a parking cycle during flight.
