Abstract

The crystal-geometric analysis of Laves phases of the A2B was carried out. The role of the ratio of atomic radii in the formation of stable superstructures was considered. It is established that the alloys with the Laves phases C14 have a high fill factor of space, which greatly exceeds the packing factor equal to 0.74 for pure metals with the hcp lattice. It is shown that the most numerous group includes alloys, which has a linear relation between the coefficients of space-filling and superstructure contraction.
