英文摘要
In this study, small tensile test machine was inserted in beam line of tandem type accelerator. After the 2. 4 MeV Fe2+ ion irradiation, the microstructure and hardness changes of the specimens with and without stress conditions were studied. In without stress, formation of small interstitial typed dislocation loop is prominent in matrix and also in the vicinity of dislocation in Fe-1. 4wt% Mn alloy. The radiation induced hardening of the samples with stress condition was more prominent than without stress condition at room temperature. But at 563K, the effect of stress on hardness changes is minor. The study revealed that the formation of interstitial type dislocation loops which enhanced by Mn addition was essential for irradiation hardening of these samples in with and without stress conditions.
