<strong>Grain</strong> <strong>Boundary</strong><br />
Diffusion<br />
• Especially for high symmetry<br />
boundaries, there is a very<br />
strong anisotropy of diffusion<br />
coefficients as a function of<br />
boundary type. This<br />
example is for Zn diffusing in<br />
a series of symmetric<br />
tilts in copper.<br />
• Note the low diffusion rates<br />
along low energy<br />
boundaries, especially Σ3.
