镁合金为轻质结构提供了很大的潜力，但由于其低耐腐蚀性，其应用范围受到限制。在本研究中，抗蠕变合金DieMag 422和AE 42的腐蚀疲劳行为进行了表征和比较。在这种情况下，在氯化钠溶液中的试样的疲劳性能，以及在同时恒电流阳极极化进行了评估，在恒定振幅测试。结果与合金的腐蚀行为，这是在仪器浸泡试验中研究。通过光学显微镜和扫描电子显微镜观察到腐蚀和变形引起的微观结构变化，从而全面了解腐蚀疲劳过程的结构-性能关系。腐蚀疲劳强度随腐蚀冲击的降低与调整后的腐蚀速率有定量的关系。然而，两种材料之间的不同的腐蚀形貌被发现，导致不同的腐蚀疲劳行为的影响。
Magnesium alloys offer a high potential for lightweight construction, however their application range is limited due to their low corrosion resistance. In the present study the corrosion fatigue behaviors of the creep-resistant alloys DieMag422 and AE42 were characterized and compared. In this context, fatigue properties of specimens in sodium chloride solutions as well as under simultaneous galvanostatic anodic polarization were assessed in constant amplitude tests. The results were correlated with the corrosion behavior of the alloys, which was investigated in instrumented immersion tests. Corrosion- and deformation-induced changes in microstructure were observed by light and scanning electron microscopy, yielding a structure-property relationship for a comprehensive understanding of corrosion fatigue processes. The reduction of the corrosion fatigue strength with increasing corrosion impact could be quantitatively correlated with the adjusted corrosion rates. However, different corrosion morphologies between both materials were found, leading to varying influence on the corrosion fatigue behavior.
