Root Cause Failure Analysis
Foreign or domestic object damage to gas turbine blades (FOD or DOD)



ITEM 1-2
Root Cause Failure Analysis
Creep failure of transition pieces



ITEM 1-3
Root Cause Failure Analysis
Creep failure of a turbine blade airfoil




ITEM 1-4
Root Cause Failure Analysis
Internal creep cracks near the fracture plane



ITEM 1-5
Root Cause Failure Analysis
TMF cracks at the leading edge cooling holes (left) of a coated blade from an aero-derivative engine and a metallurgical cross section (right).



ITEM 1-6
Root Cause Failure Analysis
TMF Cracks on a vane (nozzle) revealed by dye penetrant inspection




ITEM 1-7
Root Cause Failure Analysis
Severe hot corrosion damage to power turbine blades in an aeroderivative engine




ITEM 1-8
Root Cause Failure Analysis
High-cycle fatigue failure of a large gas turbine blade. Fretting fatigue crack at a blade tip Z-notch and complete fracture at the root are shown



ITEM 1-9
Root Cause Failure Analysis
Optical and scanning electron microscope photographs of a turbine blade failed under HCF mechanism. Crack initiation was influenced by environmental attack.
