Structure maps for close-packed alloys by the Ising model

Abstract

Abstract The one-dimensional Ising model can explain the different stackings of close-packed alloys by attractive (h 2 c 2) or repulsive (ch) interactions between 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 from structural units e.g. to long-range ordered alloys with antiphase boundaries or shearing.
