Self-consistent theory for random alloys with short-range order

In a previous paper, an analytic self-consistent cluster theory for random alloys was described; the only restriction on this theory was that the site-occupation random variables be independent (i.e., no short-range order). In this paper, we demonstrate that short-range order can be naturally included in this framework, thus providing a completely general theory for calculating the properties of random alloys. Using the augmented-space approach, we show that a short-range-order calculation requires little more than performing an independent-variables computation.
