Fracture Reason Analysis on Locking Blade of 300MW Steam Turbine
By means of chemical composition analysis,mechanical properties testing,metallographicexamination,fracture analysis and so on,the fracture reason of the locking blade of 300 MW steam turbine wasanalyzed.The results showed that the fracture was high-cycle fatigue fracture,which related to the linear defects onthe surface of blade.Some preventive measures for the blade failure were brought forward.
