The defects near the surface of stainless steel were generated in two ways: (1) generated by the bombardment of energetic ions and (2) induced by the high level stress near the surface. Thus the temperature and stress distributions near the steel surface were calculated by means of our STEIPIB code, which treated with the thermal-dynamical process in the target irradiated by the IPIB. Based on these distributions, the generations and movements of these defects were discussed and compared with the experiment results. |
