An experimental system including 5 subsystems:the loading

heating

air cooling

water cooling and control subsystems

was constructed to satisfy the requirements of thermo-mechanical fatigue (TMF) experiments of single crystal hollow turbine blades.The TMF experimental system provided evidences that the stress distribution

temperature distribution

air cooling and stress/temperature spectrum on critical section of turbine blades under service conditions could be simulated simultaneously in a laboratory environment.And the TMF experiments were performed on the critical section.The results of the TMF experiments reproduced the failure model of the turbine blades.Based on these results

life prediction and failure analysis could be investigated.
