Many-atom Correlations and the Theory of Disordered Alloys

Abstract

Some recent theories of disordered alloys are discussed with particular emphasis on their application to short-range ordered alloys. Comparisons are made in the case when only two-atom correlations are present. The probability variation method of Clapp (1969, 1971) is applied to allow inclusion of n-atom correlations which are dependent on the experimentally observable two-atom correlations. It is suggested that the cell method of Tsukada (1969) may be extended in the same manner.
