摘要
通过显微分析手段，如ＳＥＭ、ＴＥＭ、成分分析及Ｘ－射线分析等，对经６０００ｈ实际运行的机车用增压器叶片（Ｋ１７合金）进行解剖分析。结果表明，Ｋ１７合金叶片产生较为严重的热腐蚀，并伴随有强化相γ＇的聚集长大。
The booster blade with 6,000 hours service was investigated with scan electron microscope(SEM), transmission electron microscope(TEM), micro-chemical composition and x-ray analysis. The experimental results show that the inactivation of K17 alloy blade is led by hotcorrosion, and with the coarsening behavior of the strengthening phase of γ'.
