英文摘要	Nanoindentation in combination with ion irradiation offers the possibility to quantify irradiation hardening due to radiation damage. Irradiation experiments for Fe-1.0wt.%Cu alloys, China A508-3 steels, and 16MND5 steels were carried out at about 100 degrees C by proton and Fe-ions with the energy of 240 key, 3 MeV respectively. The constant stiffness measurement (CSM) with a diamond Berkovich indenter was used to obtain the depth profile of hardness. The results showed that under 240 key proton irradiation (peak damage up to 0.5 dpa), Fe-1.0wt.%Cu alloys exhibited the largest hardening (similar to 55%), 16MND5 steels resided in medium hardening (similar to 46%), and China A508-3(2) steels had the least hardening (similar to 10%). Under 3 MeV Fe ions irradiation (peak damage up to 1.37 dpa), both China A508-3(1) and 16MND5 steels showed the same hardening (similar to 26%). The sequence of irradiation tolerance for these materials is China A508-3(2) > 16MND5 approximate to China A508-3(1) > Fe-1.0wt.%Cu. Based on the determination of the transition depth, the nominal hardness H-0(irr) was also calculated by Kasada method. (C) 2013 Elsevier B.V. All rights reserved.
