Title: | Diffusivity for diffusion between e and g interstitial sites in the C15 AB₂ structure | Contributor(s): | Sholl, C (author) | Publication Date: | 2005 | Open Access: | Yes | DOI: | 10.1088/0953-8984/17/8/011 | Handle Link: | https://hdl.handle.net/1959.11/6 | Abstract: | An exact algebraic expression is derived for the diffusivity for diffusion between interstitial e and g sites in cubic C15 Laves phase AB₂ in terms of four jump rates between interstitial sites. The result is for the low concentration limit of diffusing atoms and is valid for arbitrary positions of the e and g sites. The expression reduces to simple forms in some special cases. Some examples of diffusion of H in C15 intermetallic compounds are discussed. | Publication Type: | Journal Article | Source of Publication: | Journal of Physics: Condensed Matter, 17(8), p. 1329-1334 | Publisher: | Institute of Physics Publishing Ltd | Place of Publication: | United Kingdom | ISSN: | 1361-648X 0953-8984 |
