摘要	For the steels with trace silicon, the tensile properties, low-cycle fatigue properties, fatigue fracture morphologies, dislocation evolutions, and life predictions of 550TG and SD320, are investigated. It is found that cyclic hardening appears in 550TG and opposite tendency in SD320, respectively; the dislocation density decreases after fatigue experiment for the two materials. The sub-grain boundaries in 550TG and dynamic recovery in SD320 has been discussed. The dislocation planar and wavy slip in 550TG and only planar slip in SD320 can be found. For life prediction, Basquin & Manson-Coffin and hysteretic energy relationships are more appropriate. This study will be useful for the improvement of fatigue property.; For the steels with trace silicon, the tensile properties, low-cycle fatigue properties, fatigue fracture morphologies, dislocation evolutions, and life predictions of 550TG and SD320, are investigated.
