ResumoAl-4.1 wt% Mg-Li alloys containing 0.6, 1.1 and 1.7 wt% of Li were tested by an Instron type tensile machine, after 14 MeV neutron irradiation at RTNS-II for neutron fluence up to 4 × 1022n/m2 at room temperature. No appreciable changes in yield stress, tensile strength and elongation were observed for the irradiated Al-Mg-Li alloys, in contrast with other metals and alloys such as Cu, Mo, Ni, Fe, Au, TZM, ferritic steel and SUS 316, which were irradiated and tested at the same time. Microscopic observations by TEM on the specimens of irradiated alloys showed that there were no irradiation defects in the microstructure. It is concluded that Al-Mg-Li alloys are promising materials for the D-T neutron environment for the fluence levels examined in this study.
