摘要：

In this paper, we present an iterative method for analysing experimental tracer diffusivities in binary disordered alloys using the self-consistent theory of Moleko et al. (1989). The method can be used for any binary system that can be approximated by a random alloy. Some aspects of the convergence of the proposed numerical procedure are discussed. We determine tracer correlation factors and ratios of exchange frequencies from ratios of measured tracer diffusivities for the following systems: Cu-Pt, Zr-U, Mo-W, Ag-Au, Fe-Ni, Co-Ni, Cr-Ni, Cu-Ni, Fe-Pd, Pb-Tl, Nb-Ti, Mo-Ni and Fe-Mn.
