Grain Boundary Contributions to Li-Ion Transport in the Solid Electrolyte Li7La3Zr2O12 (LLZO)
, 2017The oxide with nominal composition Li7La3Zr2O12 (LLZO) is a promising solid electrolyte thanks to its high (bulk) Li-ion conductivity, negligible electronic transport, chemical stability against Li metal, and wide electrochemical window.

Boundary conditions at grain boundaries
Journal of Applied Physics, 1983Grain boundaries in polycrystalline semiconductor material are frequently idealized as surfaces possessing a characteristic surface recombination velocity. Minority carrier densities generated by external sources (electron beams, light, etc.) in polycrystalline p–n junctions must satisfy certain boundary conditions at these grain boundaries which will ...

International Materials Reviews, 1984
AbstractTheoretical and experimental work on the atomic structure of grain boundaries in metals and ionic crystals is reviewed critically. The dislocation and O-lattice models are described and their usefulness is assessed with reference to a worked example.

Grains, grain boundaries and interfaces
2004The topic of grains and grain houndaries is extremely vast and covers many different concepts, involving not only the associated microstructural features, hut also the effects on material characteristics such as corrosion resistance and mechanical properties.

Metallurgical and Materials Transactions B, 1998
A chronological summary is given of the various types of grain boundary fracture found in metals. In each case, there is an impurity that adsorbs at the new (fracture) surface being formed. For the case of Fe-P alloys, a quantitative argument can show that adsorption of phosphorous on the free surface greatly reduces the barrier to void nucleation ...

Instability of grain boundary grooves due to equilibrium grain boundary diffusion
Acta Metallurgica et Materialia, 1991Abstract All previous theoretical investigations on grain boundary grooving are based on the assumption, that the grain boundary does not participate in the material transport. In the present paper it is shown theoretically and experimentally for the first time, that by removing this restriction one obtains completely different groove profiles in ...

Grain boundaries in recrystallization
Canadian Metallurgical Quarterly, 1974AbstractIn this brief survey, the theoretical models for nucleation of new grains in annealed cold-worked metals are reviewed in the light of recent researches in the author's laboratory. The importance of strain-induced boundary migration is gradually emerging.

Viscous grain-boundary sliding and grain rotation accommodated by grain-boundary diffusion
Acta Materialia, 2005When the sliding of a viscous grain boundary is accommodated by grain-boundary diffusion, we evaluate the sliding rate and the stress distribution on the boundary, by employing the energy-balance method developed by Mori et al. [Mori T, Nakasone Y, Taya M, Wakashima K. Phil Mag Lett 1997;75:359 and Mori T, Koda M, Monzen R, Mura T.

AbstractGrain boundary engineering is based on the fact that special grain boundaries (i.e. low Σ CSL) may have beneficial physical and chemical properties. It is now possible to increase and characterize the fraction of low Σ interfaces in polycrystalline materials, thereby improving their bulk properties by controlling the material and processing ...
