Incoherent interface
WebApr 11, 2024 · The formation of ledges with coherent interfaces could be due to their lower energy than those with an incoherent interface. Therefore, the growth of particles is expected to occur predominantly by the motion of incoherent interfaces with high mobility [39].

WebJul 19, 2024 · There are some precipitates that undergo transition from a coherent to semi-coherent state during growth. An example of such a precipitate in steel is carbide with a NaCl-type structure, such as TiC and NbC. The interface energy between carbide precipitate and iron is obtained via large-scale first-principles electronic structure calculation. The … WebMar 25, 2024 · Incoherent interfaces with no degree of coherence at all, or even be an extreme subset of semicoherent interfaces, are a perfect sink for point defects. However, incoherent heterogeneous interfaces are less observed in eutectic alloys [18]. For the most common types of heterogeneous interfaces in eutectic alloys, the coherent interface ...
