摘要: 本文研究了自来水和3.5%NaCl水溶液分别在全浸和干湿交替状态下对热轧双相钢疲劳性能的影响.结果表明:与空气中的疲劳寿命相比,腐蚀环境有不同程度的降低作用,并以喷雾盐水影响最大.在相同腐蚀条件下,环境的影响随应力幅的降低而增强.马氏体抗疲劳断裂的能力高于铁素体.试样表面和断口的观察结果发现,腐蚀疲劳裂纹萌生与腐蚀坑密切相关,蚀坑以阳极溶解方式形成.
关键词 腐蚀疲劳裂纹萌生裂纹扩展腐蚀坑干湿交替    
Abstract:Corrosion fatigue behaviour of an as-rolled dual-phase steel has beeninvestigated in tap water or 3.5%NaCl agueous solution under full immersion andintermittent wetting. It was found that in comparison with the data in air, expo-sure to either tap water or salt water results in a substantial reduction in fatiguelife and intermittent wetting later shows the most harmful effects. However, underthe same aggressive condition, the corrosion environments become more and moreharmful while the stress level decreases. A combined observation of fracture surfacewith the flat free surface in SEM shows that corrosion fatigue cracks initiateoften at corrosion pits resulted from the anodic dissolution. In addition, the inter-action between hydrogen and crack tip is considered another important factorwhich controls the crack initiation and propagation in corrosion fatigue. The mar-tensite exhibits a higher resistance to corrosion fatigue than the ferrite matrix.
Key wordscorrosion fatigue    crack iniciation    propagation of crack    corrosion pits    intermittent wetting
