| Abstract: | 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'. |
