Description

Five kinds of ferritic stainless steels were irradiated at 300 K, 473 K and 673 K with 14 MeV neutrons to a fluence of 1.3 x 1018 n/cm2 and were irradiated with fission neutrons at about 600 K to a fluence of 5 x 1018 n/cm2. Micro-bulge tests, micro-Vickers hardness tests and electron microscopy were used to characterize the radiation damage. Many radiation induced defect clusters were observed and the temperature dependence and the fluence dependence of these defect clusters suggest they are mostly vacancy type. Corresponding to the microstructural changes irradiation softening was observed. (orig.)
