摘要：

This work presents results on the influence of neutron irradiation to a dose level of 3 dpa at the irradiation temperature of 150 and 300 degrees C on mechanical properties, structure, fracture character and electrical resistivity of the GlidCopAl25IG and CuCrZr IG copper alloys. The investigations made it possible to obtain, for the first time, the dose dependencies of strengthening and embrittlement of alloys. as well as changes in materials electric conductivity in the operation temperature range of ITER materials (150-300 degrees C). As a result. the representative data were obtained for the substantiating the radiation life time of copper alloys in the dose-temperature range expected for ITER. (c) 2005 Elsevier B.V.
