Self-ion irradiation in combination with nanoindentation offers the possibility to characterize irradiation damage in a broad range of irradiation temperature and fluence. Nanoindentation results are reported for Fe-Cr alloys containing 2.5 to 12.5 at% Cr irradiated at ambient and elevated temperatures. The investigation also comprises dual-beam ion irradiations. The effects of indentation load, Cr content, fluence and irradiation temperature are discussed. We have found cases of both broad consistence with and deviations from reported trends. Hardening features are characterized by means of TEM. The results are compared with TEM, SANS and hardness data reported for neutron-irradiated conditions of the same alloys.
