Abstract
The effects of neutron irradiation below 3.6 x 1022 neutronsJcm2 (>0.1 MeV) and 5.8 x 1022 neutronsJcm (thermal, < 0.414 eV) on the microstructure and creep-rupture properties at 50°C of the 5052 aluminum alloy were determined. Irradiation-induced strengthening is attributed to the formation of β’ Mg2Si precipitate and dislocation loops. Total creep-rupture elongations before irradiation were over 25 pct, while irradiated specimens strained only about 1 pct. The loss of ductility was accompanied by a propensity for intergranular fracture.
