| Abstract: | The fractured bolt used in 50 MW turbine of Fushun power plant has been analyzed. It revealed that alternating stress in long time cause the bolt fatigue failure, meanwhile the failure process was also effected by superheating steam. Finally some methods for monitoring the bolts in service was proposed. |
