Atomic-level structure and structure–property relationship in metallic glasses

YQ Cheng, E Ma - Progress in materials science, 2011 - Elsevier
The structure of metallic glasses (MGs) has been a long-standing mystery. On the one hand,
MGs are amorphous materials with no long-range structural order; on the other hand …

The role of local structure in dynamical arrest

CP Royall, SR Williams - Physics Reports, 2015 - Elsevier
Amorphous solids, or glasses, are distinguished from crystalline solids by their lack of long-
range structural order. At the level of two-body structural correlations, glassformers show no …

The relationship of dynamical heterogeneity to the Adam-Gibbs and random first-order transition theories of glass formation

FW Starr, JF Douglas, S Sastry - The Journal of chemical physics, 2013 - pubs.aip.org
We carefully examine common measures of dynamical heterogeneity for a model polymer
melt and test how these scales compare with those hypothesized by the Adam and Gibbs …

H Zhang, DJ Srolovitz, JF Douglas… - Proceedings of the …, 2009 - National Acad Sciences
Polycrystalline materials are composites of crystalline particles or “grains” separated by thin
“amorphous” grain boundaries (GBs). Although GBs have been exhaustively investigated at …
