摘要：

In the present paper a recent six frequency model advanced hy the authors for describing diffusion in the L1(2) structure is used in the strong order limit to analyse certain aspects of the tracer diffusion in Ni3Al and Ni3Ge. Given information about the tracer diffusion coefficients and composition it is possible to gut limits on the exchange frequencies and to estimate the level of order in terms of the exchange frequencies.
