Abstract

The increasing role of interfaces with decreasing scale is particularly important for small inclusions, grains or precipitates. In this work, we present a brief review of some of our recent TEM investigations of faceted singular interfaces and interface junctions in crystals. Direct observations by high-resolution electron microscopy allow us to relate the size, shape, and local interface structure to the behavior of nanoscale inclusions. The effect of facet junctions on equilibrium shapes of inclusions, on the structure of grain boundary grooves at surfaces and on grain-boundaries in anisotropic bicrystals are illustrated with examples from recent work by this group.
