Aluminum irradiated at approximately 60 °C by neutrons is examined by transmission electron microscopy. Small dislocation loops and larger dislocation rings form during an exposure of 3 x 10¹⁸ nvt (E > 1 Mev) and increase in number with increasing irradiation dose. It is suggested that the small loops are prismatic loops, which arise from the clustering and subsequent collapse of vacancies produced by neutron bombardment. Dislocations that encounter prismatic loops frequently form rings about the loops or other obstacles.
