| 英文摘要 | High-cycle fatigue tests of compacted graphite iron (CGI) at 25 degrees C, 400 degrees C and 500 degrees C were performed. The corresponding fatigue damage mechanisms were investigated by the observations on fractographies and longitudinal section morphologies of typical samples. The results show that the decreasing rate of fatigue strength from 400 degrees C to 500 degrees C is higher than that from 25 degrees C to 400 degrees C. The fatigue strength coefficient of S-N curve fitted with the Basquin relationship decreases from 25 degrees C to 400 degrees C and increases from 400 degrees C to 500 degrees C; while the fatigue strength exponent performs in an inverse tendency. These are resulted from plastic deformation mode transition of the ferrite at the tip of the crack induced by the graphite debonding: slip band at 25 degrees C and 400 degrees C to grain boundary sliding at 500 degrees C. Finally, the influences of carbide on fatigue properties were discussed. |
