Effect of serrated grain boundary on stress corrosion cracking of Alloy 600
The effect of a serrated grain boundary on stress corrosion cracking (SCC) of Alloy 600 was investigated in terms of improvement of SCC resistance. Serrated grain boundaries and straight grain boundaries were obtained by controlled heat treatment.

Direct observation of nm-scale Mg- and B-oxide phases at grain boundaries in MgB2 [PDF]
Here we describe the results of an atomic resolution study of the structure and composition of both the interior of the grains, and the grain boundaries in polycrystalline MgB2. We find that there is no oxygen within the bulk of the grains but significant oxygen enrichment at the grain boundaries.

We present a computational approach for identifying the important descriptors of the ionic conductivities of lithium solid electrolytes. Our approach discriminates the factors of both bulk and grain boundary conductivities, which have been rarely ...

Continuation and Bifurcation of Grain Boundaries in the Swift-Hohenberg Equation [PDF]
We study grain boundaries between striped phases in the prototypical Swift-Hohenberg equation. We propose an analytical and numerical far-field-core decomposition that allows us to study existence and bifurcations of grain boundaries analytically and numerically using continuation techniques.

In this study, we simulated the effects of the anisotropy field (Hk) dispersion of the grains (the main phases and the deterioration layers) for a NdFeB magnetic powder on Hc and squareness ratio in consideration of the magnetic properties of the grain ...
