Effect of high doses of neutron irradiation on physico-mechanical properties of copper alloys for ITER applications

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 °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.
