Abstract
The stress field of pitting corrosion at different depths under tensile load was analyzed by ANSYS finite element method. It was found that the strength of stress field and strain field inside the corrosion pit was much higher than the average level of matrix. Therefore, the corrosion pit will fail first under the action of applied load. Based on the study of pitting corrosion, the mechanism of pitting corrosion crack propagation of magnesium alloy welded joints was described with a model, and the variation of residual strength was revealed.
