| Abstract Scope |
While the relationship between defect distribution and coherency strain accommodation is well understood for simple flat boundaries, how interfacial defects are distributed to accommodate strain in cases where there is a large change in boundary inclination is less well understood. This is important because grain boundary behavior is largely dependent on the local changes in curvature. This work utilizes high resolution STEM to resolve localized grain boundary junction changes from {100}//{110} to {111}//{112} inclinations in 90° <110> Au bicrystals. By quantifying the distribution of disconnections at these junctions our observations provide better understanding of the strain accommodation mechanisms at nonplanar boundaries.
