Popis:	In this paper the nature of the relationships between the low-index Warren-Cowley short-range order (SRO) parameters in a face centered cubic (f.c.c.) stoichiometric A 0.5 B 0.5 binary alloy is discussed. A region of allowed combinations of SRO parameters describing ordering in two nearest coordination spheres is demonstrated and its connection with the Clapp-Moss diagram is explored. Evolution paths of ordering in the SRO space obtained by Monte Carlo simulation using an Ising model with first- and second-nearest-neighbor pairwise interaction parameters are presented and discussed. A method is proposed for the estimation of the interaction parameters from the initial behavior of the evolution path of a disordered system.
