Abstract�� High cycle fatigue and low cycle fatigue properties and fracture behavior of GH2132 were investigated under different temperature, stress intensity factor and stress. The effect of each parameter was analyzed to determine the interaction on fatigue life. It was found that the parameter, which affected the life mostly, was different at different experimental conditions. Combining results by scanning electronic microscopy, the reason of the interaction was revealed.
Keywords�� fatigue life   fracture mechanism   interaction of many parameters   fracture appearance analysis
