The effect of carbon content on the microstructural evolution and thermal fatigue behavior of Ni-Cr-Fe-Mo alloy with different carbon content was carried out at temperature ranging from 20°C to 920°C. The microstructure evolution was detected and the length of thermal fatigue cracks was measured. The results revealed that all the alloys are mainly composed of γ phase and carbides. With the increase of carbon content, the volume fraction of carbides increase and the morphology varies from blocky to script-like and sheet-like. The microstructural features exert influence on the thermal fatigue cracks of the alloys with different carbon content. Considering the thermal fatigue properties, the optimum carbon content of the Ni-Cr-Fe-Mo alloy superalloy should be below 0.08wt.%.
