在文献中的实验扩散数据，结合现有的基于CALPHAD的热力学参数，被用来评估的Ti-Al-V系统的bcc相的原子迁移率通过使用DICTRA软件。从计算和实验扩散系数之间的全面比较，获得了良好的协议。原子迁移率数据库的开发进一步验证了适当的预测一些扩散行为所造成的相互扩散，特别是扩散对的浓度分布。
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.
