Abstract

The available experimental diffusion data of the bcc phase of the Ti-Sn binary alloys and Ti-Al-Sn ternary alloys have been critically evaluated to assess the atomic mobility parameters of bcc Ti-Al-Sn ternary alloys employing the diffusion-controlled transformation phenomenological treatment. The calculated interdiffusion coefficients in the bcc Ti-Sn binary and Ti-Al-Sn ternary alloys show a reasonable agreement with the experimentally extracted interdiffusion coefficients. The predicted composition profiles and diffusion paths reasonably represent those occurring in the Ti-Sn binary and Ti-Al-Sn ternary diffusion couples, thus validating the mobility database assessed in the present work.
