Dynamic relaxations and relaxation-property relationships in metallic glasses

WH Wang - Progress in Materials Science, 2019 - Elsevier
Dynamic relaxation is an intrinsic and universal feature of glasses and enables fluctuation
and dissipation to occur, which induces plentiful behaviour, maintains equilibrium, and …

Noble-metal-based high-entropy-alloy nanoparticles for electrocatalysis

X Huang, G Yang, S Li, H Wang, Y Cao, F Peng… - Journal of Energy …, 2022 - Elsevier
Since the two seminal papers were published independently in 2004, high-entropy-alloys
(HEAs) have been applied to structural and functional materials due to the enhanced …

Deformation of metallic glasses: Recent developments in theory, simulations, and experiments

TC Hufnagel, CA Schuh, ML Falk - Acta Materialia, 2016 - Elsevier
We review recent research into elastic and plastic deformation of metallic glasses, with an
emphasis on making connections between developments in theory and simulation (largely …

Shear bands in metallic glasses

AL Greer, YQ Cheng, E Ma - Materials Science and Engineering: R: Reports, 2013 - Elsevier
Shear-banding is a ubiquitous plastic-deformation mode in materials. In metallic glasses,
shear bands are particularly important as they play the decisive role in controlling plasticity …

Structure-property relationships from universal signatures of plasticity in disordered solids

ED Cubuk, RJS Ivancic, SS Schoenholz, DJ Strickland… - Science, 2017 - science.org
When deformed beyond their elastic limits, crystalline solids flow plastically via particle
rearrangements localized around structural defects. Disordered solids also flow, but without …

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 …

Tuning order in disorder

E Ma - Nature materials, 2015 - nature.com
Recent research has revealed considerable diversity in the short-range ordering of metallic
glass, identifying favoured and unfavoured local atomic configurations coexisting in an …

Full icosahedra dominate local order in Cu64Zr34 metallic glass and supercooled liquid

J Ding, YQ Cheng, E Ma - Acta materialia, 2014 - Elsevier
Extensive molecular dynamics simulations were carried out to monitor the development of
icosahedral order in Cu 64 Zr 34 liquid and metallic glass (MG). This study illustrates that at …

Structural processes that initiate shear localization in metallic glass

AJ Cao, YQ Cheng, E Ma - Acta Materialia, 2009 - Elsevier
For crystalline metals, the structural carriers (dislocations and twins) of plasticity have been
well characterized. In contrast, the structural processes responsible for the localized shear …
