摘要
针对航空发动机涡轮叶片的工作环境和使用要求,介绍了提高涡轮叶片耐温能力的两种途径,即加强叶片冷却和提高叶片材质自身的耐温性能。文中着重评述了用作叶片材料的合金及其制造工艺的研究进展与发展趋势。
Based on the working situation of aero engine blades, two methods toimprove the high temperature properties of the turbine blades are reviewed, i. e. to develope high efficient cooling blades, and optimize the compositions and processings of the blade alloys. The development of the blade alloys is emphasized, their furfure is also discussed in the paper.
