Diffusion in Ordered Alloys, Symposium Held in Chicago, Illinois on November 3 - 4, 1992

Abstract

Diffusion in ordered binary alloys has been treated using the pair- approximation of the Path Probability Method (PPM) based on an atomistic model. The effect of the atomic interaction on the ordering behavior and its influence on transport properties have been clarified. Compositional dependences of both the intrinsic diffusion and interdiffusion coefficients, correlation factor, and thermodynamic factor agree very well with results from Monte Carlo simulations. The calculated properties also show qualitative agreement with the experimental data on diffusivity, activity, and creep in NiAl system
