Abstract Scope |
Recent examinations of grain boundary mobility have demonstrated some very interesting phenomena, where grain boundaries can exhibit thermally activated and anti-thermal temperature dependence as well as a diversity of atomic migration mechanisms. Most of these studies focus on examining the migration behaviors associated with the minimum energy structure of a grain boundary. Since it is known that grain boundaries can take on a range of atomic structures, we examine the diversity of behaviors associated with these metastable grain boundary configurations. Initial examination indicates that the behaviors fall into groups of structures that exhibit similar behaviors. We will present on these observations as well as the application of machine learning techniques to find the correlations between the grain boundary structures and their observed behaviors. |
