In common with other elemental actinides, metallic uranium exists in several allotropic forms which differ from each other by complex but subtle atomic rearrangements. This article reviews progress in understanding the successive phase transformations from the perspective of soft-mode instabilities, and includes discussions on alpha-uranium, incommensurate modulation, lock-in transformations, and ghost lattices.
