摘要：

HT-9 steel samples have been irradiated with fast neutrons (E > 0.1 MeV) to a low dose (1.2 x 10(-3) dpa). Microstructure of the unirradiated and irradiated samples has been characterized by X-ray diffraction line profile analysis using different model-based approaches. The domain size and density of dislocations of the irradiated steel have been estimated. Different types of tensile tests have been carried out at room temperature to assess the changes in mechanical properties of HT-9 steel due to neutron irradiation. (C) 2013 Elsevier Ltd.
