Grain-boundary segregation and precipitates in La2O3 and Pr2O3 doped SnO2 center dot CoO-based varistors
(Elsevier B.V., 2003-10-01)
Structural heterogeneities in SnO2.CoO-based varistors were analyzed by transmission electron microscopy. In SnO2.CoO-based system doped with La2O3 and Pr2O3 two kinds of precipitate phases at grain boundary region were ...

Effect of manganese on grain boundary segregation of sulfur in iron
(Elsevier Science, 2007-05)
The ASED-MO theory was used to study the electronic effects of S and the S-Mn couple upon the chemical embrittlement of Fe grain boundaries. The results obtained for S alone in a model of grain boundary (GB) are consistent ...
The effect of electron scattering from disordered grain boundaries on the resistivity of metallic nanostructures
(2015)
We calculate the electrical resistivity of a metallic specimen, under the combined effects of electron scattering by impurities, grain boundaries, and rough surfaces limiting the film, using a quantum theory based upon the ...
Elastic instability of grain boundaries and the physical origin of superplasticity
(American Inst of Physics, 2000)
The dependence of the superplastic flow on the efficiency of grain boundaries for capturing and releasing vacancies is demonstrated. It is emphasized that this flow is dependent mostly on the sensitivity of this ability ...
