Abstract
High cycle fatigue and low cycle fatigue properties and fracture behavior of GH2132 alloy were investigated with different temperature, stress intensity factors 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, is different under different experimental conditions. Combining the results obtained by scanning electron microscopy, the reason of interaction was revealed.
