Bulk diffusion enhancement due to grain-boundary migration
- 72 Downloads
This paper reports bulk diffusion enhancement under conditions where grain-boundary migration and grain growth, or grain growth only take place during the time of the diffusion experiment.
Although a substantial contribution to diffusion takes place through grain-boundaries the penetration curves measured remain Gaussian, as suggested by Balluffi and Ruoff . The apparent enhancement measured is about a factor of two. However, it is shown that the real enhancement due to migration of grain-boundaries during the diffusion experiment may be as large as a factor of fifty.
