[Display omitted] We analyze the structural evolution at the arriving crystal/liquid interface in deeply undercooled elemental metallic liquids. Specifically, we use molecular dynamics simulations to monitor the intermediate dumbbell-interstitial-like pairs (DILPs) preceding the growing BCC crystal....
