摘　　要：就烟气轮机用Waspaloy合金涡轮叶片热处理工艺的选择,分析了合金经2种不同的热处理工艺处理后,组织与性能表现出的不同特点。结合叶片的实际工作条件进行了综合分析与讨论。A superalloy, Waspaloy, was selected as a typical blade alloy for the advanced flue gas turbine. Two different heat treatments which resulted in the different microstructure and mechanical properties were investigated and compared. However, the blades with these two heat treatments have been successfully performing for more than one year. A detailed discussion was given in this paper.
