| Abstract: | With the increasing in inlet temperature of new types of aeroengines, experiments were carried out to study the thermal fatigues of representative wrought superalloys, especially some newly developed ones. The influence of testing temperature on the thermal fatigue life was investigated to give the relationship between test temperature and fatigue life. The effects of test temperature on thermal fatigue crack propagation and the fracture mode of thermal fatigue of these alloys were also investigated. |
