摘要: 水介质会延迟疲劳裂纹的扩展,此作用随介质中氧浓度的增加而增强,这是由于裂纹内的腐蚀产物以及粗糙的断口表面促使裂纹提早闭合。文中还用裂纹尖端氧浓度计算公式来解释水介质中da/dN的变化规律。

Abstract：The corrosion fatigue behaviour of 55SiMnMo steel in aqueous media were studied. The fatigue fracture was retarded by the medium in such a manner that the crack propagation was retarded with increasing oxygen concentration in the medium. The retardation was attributed to the early crack closure brought about by both the corrosion products wedging into the cracks and the rough fracture surfaces. The crack propagation rates (da/dN)in the aqueous medium were estimated in terms of the calculated oxygen concentrations at the crack tip.
