Abstract : A brief summary is given of a research program which developed three types of experimental information: (a) precision data on the structure and unit cell dimensions of metallic and non-metallic materials over a range of temperatures, (b) information on phase changes and on phase diagrams for the region of temperature below room temperature for solids with van der Waals binding, and (c) transformation characteristics and imperfection characteristics for some of the more interesting van der Waals solids.
