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...

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。

The fatigue crack propagation of dual-phase microstructures was investigated in 42CrMo steel. The results showed that the dual-phase structures could significantly increase the crack initiation and propagation time and decrease the propagation rate.The high fatigue properties were found to be related with higher crack closure stress,rough fracture surface and tortuousity of crack path.

The fatigue crack propagation of dual-phase microstructures was investigated in 42CrMo steel. The results showed that the dual-phase structures could significantly increase the crack initiation and propagation time and decrease the propagation rate.The high fatigue properties were found to be related with higher crack closure stress,rough fracture surface and tortuousity of crack path. Based on the analysis of fatigue fracture mechanism,it was concluded that the superior fatigue crack growth resistance of the dualphase structure was attributed to the roughness-induced crack closure effect and deflection effect as well, which reduced the effective driving force at the crack tip.

研究了42CrMo钢亚温淬火及二次淬火两种双相组织的疲劳裂纹扩展行为,结果表明,亚温淬火双相组织可显著提高裂纹萌生抗力,降低扩展速率;较高的疲劳性能与裂纹尖端闭合应力、断口表面粗糙度以及裂纹扩展路径弯折程度有关。断裂力学分析表明,粗糙度诱发裂纹闭合效应及裂纹路径弯折效应是提高裂纹扩展抗力的主要因素,同时得到上述两种效应对裂纹扩展速率影响的表达式。

The mechanical properties and fatigue crack growth behavior of 20G and 15CrMo steels after hydrogen attack at different temperatures under the hydrogen presence of 18MPa for 240h have been investigsted.The effeCt of the stress ratio on the fatigue crack growth behavior of 20G steel after hydrogen attack has been examined. The results show that the effect of hydrogen attack on the fatigue crack behavior of 20 G steel could be attributed to two factors,namely,the hydrogen attack damage to material and the crack closure caused by rough fracture surface due to hydrogen attack.On the contrary,the only factor decisive to fatigue crack behavior of 15CrMo steel are severe decarburization. The stress ratio have great influence on fatigue properties of 20G steel after hydrogen attack.
