Relaxation of atoms in the tungsten Σ3(111) grain boundary with and without boron interstitials
(2001)
We study lattice reconstruction of tungsten near the Σ3(111) grain boundary (GB) and calculate relaxations of atoms in the vicinity of the Σ3GB in tungsten with and without boron interstitials. Monte Carlo (MC) atomistic ...
Schottky-type grain boundaries in CCTO ceramics
(Pergamon-Elsevier B.V. Ltd, 2011-10-01)
In this work we studied electrical barriers existing at CaCu(3)Ti(4)O(12) (CCTO) ceramics using dc electrical measurements. CCTO pellets were produced by solid state reaction method and X-ray diffractograms showed which ...
Electrical Properties at Grain Boundaries Influenced by Cr3+ Diffusion in SnO2.ZnO.Nb2O5-Films Varistor Prepared by Electrophoresis Deposition
(2014)
SnO2-based varistors are strong candidates to replace the ZnO-based varistors due to ordering fewer additives to improve its electrical behavior as well as by showing similar nonlinear characteristics of ZnO varistors. In ...

Temperature induced disorder in β-Zr
(Sociedad Mexicana de Fisica, 1998)
The behavior of free surfaces and of grain boundaries of a bcc Zr system, close to the melting temperature, are investigated using molecular dynamics in combination with a tight-binding potential. Our system consists in ...
A method for the digital image analysis of ceramic grains based on shape factor segmentation
(2003-03-13)
A very simple and robust method for ceramics grains quantitative image analysis is presented. Based on the use of optimal imaging conditions for reflective light microscopy of bulk samples, a digital image processing routine ...
