摘要：

The most susceptible site for pit initiation was the retained delta ferrite/austenite interface. Microanalysis results disprove the chromium depletion theory. The most likely explanation is a segregation of impurities such as sulfur or phosphorus to the interface during the nonequilibrium solidification process associated with weldments. The passive film over the interface as well as repassivation kinetics are degraded by impurities.
