The nanoindentation behavior of P92 steel with thermomechanical treatment under 3.5 MeV Fe13þ ion irradiation at room temperature, 400 and 700 C was investigated. Pop-in behavior is observed for all the samples with and without irradiation at room temperature, while the temperature dependence of pop-in behavior is only observed in irradiated samples. The average load and penetration depth at the onset of pop-in increase as the irradiation temperature increases, in line with the results of the maximum shear stress. Irradiation induced hardening is exhibited for all irradiated samples, but there is a significant reduction in the hardness of sample irradiated at 700 C in comparison to the samples irradiated at room temperature and 400 C. The ratio of hardness to elastic modulus for all samples decreases with increasing penetration depth except for samples at 700 C. With the increasing of irradiation temperature, the ratio of the irreversible work to the total work gradually decreases. In contrast, it increases for samples without irradiation
