Incoherent boundary
WebA coherent interface is formed when the two crystals or part of the crystal has a good ‘match’ and the two lattices are continuous across the interface. This happens when the interfacial plane has the same atomic configuration in both phases, e.g. {1 1 1} in fcc and … The simplest boundary is the symmetrical tilt boundary.
