英文摘要	As carbon steel immersed in seawater with loading, particularly with defect, its performance lead degradation and reduction in bear capacity. For the specimen of carbon steel immersed in seawater with notch and defects, its macro-mechanical properties was tested and also analyzed with electron microscopy equipment. The fracture behavior of specimen was analyzed in different test conditions, and their bearing capacity was contrast each other for loading before and after soaking. Some relation curves are gotten as the curve of crack tip opening displacement and loading, or relation between loading and the displacement of loading point for specimen before or after soaking in seawater. The specimen with plastic zone of crack-tip was soaked in seawater for short-term, according to the analysis of experimental results, the length of plastic curve between reloading and displacement is become shorter, and the material is more brittle. In the area of meso-analysis, fracture performance of seawater corrosion steel were investigated by electron microscopic observation, and checked the difference of characteristics parameters and meso-morphologies of material specimen. As to plastic, the effect of seawater on carbon steel dislocation and slip were also researched in the paper.
