Webbook [21]. Such mechanisms—interfacial sliding, grain boundary diffusional creep and rotational deformation— effectively operate in nanocrystalline solids, first of all, due to the presence of a very large number of grain boundaries [19–21]. In the context discussed, it is natural to think that these specific deformation mechanisms can WebApr 15, 2024 · Grain growth has long been described as motion by mean curvature (i.e., curvature flow) (1–3); grain boundaries (GBs) migrate toward their center of curvature, …
WebMay 1, 2009 · In particular, in 2D, assuming (a) isotropic GB energies and (b) local equilibrium at triple junctions, the rate of growth of a grain can be shown to be purely driven by its topology, namely, the number of its sides [ 7, 8 ]; in 3D, under the same assumptions, the growth rate is no longer purely topological but is more involved [ 9 ]. WebJun 15, 2024 · A typical quadruple node (QN) of triple junctions (TJs) of grain boundaries (GBs) in a Eu 2+-doped KCl 0.52 Br 0.48 solid solution is investigated from the geometrical point of view by epifluorescence microscopy using the doping ion as a fluorochrome. The excitation and fluorescence optical properties of the fluorochrome were previously …
Webidentical [7].) There are four types of triple junctions that can occur in a material, i.e., 0 low-Σ CSLB, 1 low-Σ CSLB, 2 low-Σ CSLBs, and 3 low-Σ CSLBs coming together. GB connectivity, being often simulated with percolation theory, quantitatively evaluates the frequency of resistant triple junctions that have more low-Σ CSLBs coming ...
