The effects of alloying elements on irradiation hardening behavior of various Fe-based binary alloys irradiated with Fe3+ ions were investigated by using the nano-indentation technique. Ion-irradiations with 6.4 MeV Fe3+ were performed on Pure-Fe, Fe-1Cr, Fe-1Mn, Fe-1.5Mn, Fe-1Ni, Fe-1Cu, and Fe-1Mo to nominal displacement damage levels of 0.1, 0.3 and 1 dpa, at a damage rate of 1 × 10-4 dpa/s at 290 °C. Significant irradiation hardening was observed in the Fe-1Mn, Fe-1.5Mn and Fe-1Ni as well as in the Fe-1Cu, but not in the Pure-Fe, Fe-1Cr and Fe-1Mo, after irradiation to 1 dpa at 290 °C. The dose dependence of the irradiation hardening was well explained for all the alloys by the saturation fitting model. Microstructural observation suggested that irradiation induced matrix defects in Fe-Mn binary alloy promoted the irradiation hardening.
