摘要：

In order to discuss the effect of corrosion results on fatigue properties of corroded steel, the morphology measurements and fatigue tests were performed to 10 corroded steel specimens obtained by artificial accelerated corrosion tests. And the corroded morphological characteristics and fatigue fracture of corroded specimen were studied. The results found the fracture mode and fatigue life were closely associated with the corroded morphological characteristics, especially for the fracturing source corrosion pit (FC-corrosion pit). So, based on the systematically analysis, the fatigue life prediction method of corroded steel was proposed.
