| Abstract: | In situ TEM observations on the behaviour of dislocation configuration ahead of a loaded crack tip in 310 stainless steel before and after anodic dissolution were carried out in running tap water by specical constant-displacement loading stage.After eliminating the effect of creep at room temperature,the anodic dissolution may induce the dislocation emission, multiplication and motion onto 310 stainless steel in water. The SCC in water at room temperature could occur in the thin foil 310 stainless steel specimen. |

| Keywords: | anodic dissolution dislocation emission in situ TEM observation |
