WebTheir boundaries are of two general types coherent and incoherent. The coherent boundaries are usually also symmetric, so they offer little resistance to dislocation motion …
WebApr 20, 2024 · Grain boundaries (GBs), as a major microstructure feature, play important roles in the functions and performances of polycrystalline metals [ 1 ]. Twin boundaries (TBs), as a special type of GBs, have attracted the most attention, especially for metals with low or medium stacking-fault energies. 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 …
