Incoherent interface
WebIncoherent interfaces have energy and are comparatively mobile due to the relatively larger freedom of the motion of the atoms. The shape of the precipitate is powerfully influenced … WebApr 13, 2024 · The clean nanoparticles/matrix interface indicates its incoherent nature, and the selected area diffraction (SAD, inset in Fig. 4 b) pattern demonstrates that the nanoparticle has an ordered L2 1 lattice. In contrast, the dislocation cells almost completely disappear after homogenization, as shown in Fig. 4 c.

Strain mapping based on the in situ HRTEM observation confirms that considerable strain accumulated at the interface between oxide and alloy substrate for the oxidation by O 2 ( Fig. 4, A and B ), …
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].

For the special case of a coherent, athermal transformation, we added an ...
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. WebJul 11, 2024 · Our results show that heat conduction of (SnS) 1.17 (NbS 2) n superlattices is dominated by interface scattering when the coherent length of phonons is larger than the superlattice period, indicating that incoherent phonon transport dominates through-plane heat conduction in van der Waals superlattices even when the period is atomically thin ...
WebDec 19, 2024 · This is because the incoherent interface can simultaneously serve as the source for dislocation nucleation and the barrier for dislocation motion, and thus plays a dual role of softening and hardening in the compressive deformation. Therefore, it can be expected that tuning the interface with $$ {\text{Ti}}_{2} {\text{AlN}}(10{\bar{\text{1}}}3 ...
