摘要: A more accurate life prediction for gas turbine blade takes into account the material behavior under complex thermo-mechanical fatigue (TMF) cycles normally encountered in operation. An experimental program has been carried out to address of IN738LC nickel-base superalloy. High temperature out-of-phase and in-phase TMF experiments strain control were performed on superalloy materials. Temperature interval 450-850 was applied tests. The stress-strain response cycle measured during test. mechanisms damage is discussed based microstructural evolution TMF. plastic energy pediction models history effect lives.
