Abstract

Experimental diffusion data in the literature, in conjunction with existing CALPHAD-based thermodynamic parameters, were used to assess the atomic mobilities for the bcc phase of the Ti-Al-V system by using the DICTRA software. Good agreement was obtained from a comprehensive comparison between the calculated and experimental diffusion coefficients. The atomic mobilities database developed was further validated by appropriate predictions of some diffusion behavior resulting from interdiffusion, especially the concentration profile of diffusion couples.
