Abstract

Fractographic study suggests that the locking slot of the blade has failed by fatigue. The fatigue was of low cycle-high stress type. Examination revealed that fatigue was stress related and was caused due to severe deformation of the material in contact with the locking ring. The reason for such deformation at the locking slot needs to be determined. The microstructure of the blade material was found satisfactory and there were no metallurgical abnormalities
