Abstract
On the basis of critically reviewed experimental diffusivities available in the literature, a through assessment of the atomic mobilities of Cu, Ni, and Zn in fcc Cu-Ni-Zn alloys was conducted using the DICTRA software. Comprehensive comparisons show that good agreements between the presently calculated diffusion coefficients and the experimental data were obtained. The reliability of the atomic mobilities obtained was further verified by comparing various model-predicted diffusion phenomena with the experimental information, such as concentration profiles, Kirkendall shift and diffusion paths in a series of binary and ternary diffusion couples.
