A rotor blade of titanium alloy TC11 in an aero-engine fractured at the root segment during service. Appearance observation, fracture surface observation, metallurgical structure examination, chemical composition analysis and hardness testing were carried out to find out the failure mode and cause of the fractured blade. The results show that the fracture mode of the rotor blade is high-cycle fatigue fracture. The initiation of the fatigue crack is related to local stress state of the blade, and inching wear promotes the initiation of fatigue crack.
