Failure Analysis of a Heavy Duty Gas Turbine Blade*

  • 165 Accesses

  • 3 Citations

The failure analysis of a broken blade with 25,000 EOH of operation has been carried out. The complementary analysis that consists of metallurgical and fractography techniques have been employed. The results of fractography proved that the cracks initiated from hot corrosion pits on the airfoil and propagated by hot corrosion fatigue mechanism and led to blade fracture.
