Atomic arrangements in amorphous metals and alloys are discussed in terms of continous dense random packing model structures. Constraints which may be introduced into computer generated hard sphere packings to insure tetrahedron perfection are described. The agreement between experiment and computer generated binary dense‐random‐packing‐of‐hard‐spheres models which emphasise nearest neighbor tetrahedral ordering is encouraging. Such models reproduce the observed, composition dependent structural features seen in the radial distribution functions of amorphous rare each metal − transition metal alloys.
