WebThe last type of interface that we're going to talk about is called an incoherent interface. And an incoherent interface is illustrated along the line. And what we see here is the type of interface that you would have in a grain boundary, for example, where we have broken bonds and the broken bonds are contributing to the interfacial energy. WebAug 12, 2015 · The semi-coherent interface can be regarded as the superposition of a coherent interface and a network of misfit dislocations relieving its coherency strain [ 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 ]. Interfaces, in general, are strong barriers to gliding dislocations [ 12, 13, 14, 15, 16, 17, 18, 19 ].
