Scanning transmission electron image of region beneath a spherical indent in a forsterite bicrystal from Diana Avadanii's DPhil work. The grain boundary is vertical in the center of the image. The residual spherical impression is visible at the top. Dark regions indicate significant dislocation accumulation. The bright cracks are unloading features. The mechanical and microstructural data from these experiments help elucidate how grain boundaries interact with and act as sources for lattice dislocations.
