| Abstract | Strain-controlled low-cycle fatigue (LCF) tests at a fairly high strain rate were performed on as-cast compacted graphite iron (CGI) controlled with total strain amplitude at 25, 400 and 500 degrees C. The results show that CGI has the longest fatigue life, smallest stable hysteresis loop area at 400 degrees C. The reason is that the effective bearing size of the ferrite increases from 25 degrees C to 400 degrees C because slip deformation is retarded by carbon atom diffusion and carbide formation, and decreases from 400 degrees C to 500 degrees C because of the appearance of the ferrite grain boundary sliding. That effect of temperature is associated with the elastic strain amplitude instead of the plastic strain or stress amplitudes in macroscope. Finally the corresponding improvement suggestions based on these were also proposed. |
