| 英文摘要 | Thermal aging effects on surface of 2.5 MeV Fe ion-irradiated Fe-0.6%Cu alloy were investigated using positron annihilation techniques. The samples were irradiated at 573 K to a dose of 0.1 dpa. Their thermal aging was performed at 573 K for 5, 50 and 100 h. From the results of Doppler broadening measurement, an obvious trough could be seen in near-surface region from the S parameters and inflection point form at S-W curves. This indicates changes in the annihilation mechanism of positrons in surface region after thermal aging. Coincident Doppler broadening indicates that the density of Cu precipitates in the thermal aged samples decreased, due to recovery of the vacancies.; Thermal aging effects on surface of 2.5 MeV Fe ion-irradiated Fe-0.6%Cu alloy were investigated using positron annihilation techniques.
