Abstract
The one-dimensional Ising model can explain the different stackings of clos e-packed alloys by attractive (h(2)c(2)) Or repulsive (ch) interactions bet ween metal atoms. A similar analysis explains the ordering in the hexagonal planes. The three-dimensional analysis of ordered hcp and ccp alloys shows the existence of different families of structures and the construction fro m structural units e.g. to long-range ordered alloys with antiphase boundar ies or shearing.
