Thin foil samples were prepared along its cross--section containing the pre--cracks, and the tip region of SCC was studied by analytical TEM. The observations show that there are oxides with a size of several hundreds nanometers ahead of a crack tip of SCC and around the discontinuous microcracks. Fine--probe analysis was used to determine local compositions of the oxides, indicating the oxides are Cr2O3, Fe3O4 and their mixture. Many microcracks are distributed unevenly in the oxides. Microcracks initiated discontinuously in the oxides ahead of a main crack because of a large stress concentration. The growth and connection of the discontinuous microcracks in the oxides resulted in the propagation of SCC.
