| Abstract Scope |
While the following statements may seem non sequiturs: (i)the motion of interfaces is sensitive to their structure, and (ii) microstructure evolution is influenced by interface dynamics, predicting microstructure evolution is not feasible without establishing the mechanistic links in both. This lecture is a pedagogical presentation of these links in the context of grain boundaries (GBs) and grain growth (GG). I will start with a very brief review of our current understanding of GB structure and their line defects. Next, I will address how to understand GB migration in terms of the motion of these defects and the intriguing mechanics/interface migration coupling they produce. Finally, I will surprising results demonstrating how incorporating this coupling redefines our understanding of microstructure evolution. |
