Abstract
Ion irradiation damage effects in delta (δ) Y6U1O12 were characterized using grazing incidence X-ray diffraction and transmission electron microscopy. Experimental results revealed no amorphization transformation occurs in Kr-ion irradiated Y6U1O12 to a maximum displacement damage dose of ∼50 displacements per atom at cryogenic temperature. Density functional theory calculations indicate that δ-Y6U1O12 possesses a relatively low cation antisite formation energy, which may help to explain the observed resistance of δ-Y6U1O12 to irradiation-induced amorphization of δ-Y6U1O12.
