1. Here the grain boundary analogue of Langmuir adsorption at free surfaces becomes: 2. This scheme prohibits dislocation pile-up and instead results in grain boundary diffusion. 3. Moreover, the size of the grain boundaries scales directly with particle size. 4. Grain boundary initiation and interface interaction are more common sources of dislocations.5. This means that the grain boundary will migrate towards the curvature. 6. Both Hydrogen and CO diffuse out from the grain boundaries in stainless steel. 7. The areas where crystallite grains meet are known as grain boundaries . 8. The grain boundaries and remaining crystal defects are responsible for some residual resistance. 9. Twinning is a phenomenon somewhere between a crystallographic defect and a grain boundary . 10. The excess volume is another important property in the characterization of grain boundaries .
