摘要：

Experimental diffusion data were critically assessed to develop the atomic mobility for the bcc phase of the Ti-Al-Fe system by using the DICTRA software. Good agreements were obtained from comprehensive comparisons made between the calculated and the experimental diffusion coefficients. The developed atomic mobility was then validated by well predicting the interdiffusion behavior observed from the diffusion-couple experiments in available literature. (C) 2014 Elsevier Ltd.
