Abstract The geometries of anisotropic surfaces or interfaces in polyphase or polycrystalline microstructures can display a variety of shapes that are locally in equilibrium. Anisotropy introduces edges, corners, and flat facets, as well as new types of multigrain junctions, and requires a re-examination of how we represent geometrical equilibrium. The traditional approach, that begins with the interfacial free energy γ( n ) as a function of interface normal n , assumes knowledge of data that… CONTINUE READING
