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 ]. WebMay 19, 2015 · The theory of incoherent interfaces, which includes junctions and diffusion, is in fact applicable to a more general situation where the grains are allowed to deform plastically. The resulting ...
Phonon Transport Across Coherent and Incoherent …
WebJan 5, 2024 · Coherent and semicoherent interfaces, those with little to no lattice mismatch, can form subgrains of uninterrupted columnar structures over heterophase interfaces, whereas incoherent interfaces can be highly mobile and interrupt the columnar grain structure [41,42,43,44]. Ta-Hf is a special case for coherency of interfaces, where a … 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 ... how many days between christmas and easter

Webhas been published that addressed the issues of incoherent interfaces in nanoscale metallic multilayers. Hoagland and co-workers have studied incoherent Cu–Nb interface [7,20]. That work was focused on the interaction of single, artificially introduced dislocations with the interface under essentially two-dimensional modeling conditions. WebMar 15, 2024 · Firstly, the incoherent interface could provide the source for the nucleation of primary dislocations, incepting the plastic deformation. Secondly, the incoherent interface … WebApr 30, 1991 · Mann's most famous works include the monumental The Sources of Social Power and The Dark Side of Democracy, spanning the entire 20th century.
