The results show that hydrogen can enhance dislocation emission, multiplication and motion, and increase the size of dislocation free zone (DFZ). A nanocrack of HIC will initiate and Dropagae in the DFZ when hydrogen enhanced dislocation emission and motion reach a critical condition. The reasons that hydrogen enhanced dislocation emission and motion, and the mechanism of initiation of HIC have been discussed.
