Grain-boundary kinetics: A unified approach

J Han, SL Thomas, DJ Srolovitz - Progress in Materials Science, 2018 - Elsevier
Grain boundaries (GBs) are central defects for describing polycrystalline materials, and
playing major role in a wide-range of physical properties of polycrystals. Control over GB …

Colloidal hard spheres: Triumphs, challenges, and mysteries

CP Royall, P Charbonneau, M Dijkstra, J Russo… - Reviews of Modern …, 2024 - APS
The simplicity of hard spheres as a model system is deceptive. Although the particles
interact solely through volume exclusion, that nevertheless suffices for a wealth of static and …

Poisson's ratio and modern materials

GN Greaves, AL Greer, RS Lakes, T Rouxel - Nature materials, 2011 - nature.com
In comparing a material's resistance to distort under mechanical load rather than to alter in
volume, Poisson's ratio offers the fundamental metric by which to compare the performance …

Grain size and grain-boundary effects on diffusion and trapping of hydrogen in pure nickel

A Oudriss, J Creus, J Bouhattate, E Conforto, C Berziou… - Acta Materialia, 2012 - Elsevier
The impact of grain size on hydrogen diffusion and trapping mechanisms has been
investigated for a wide range of grain size of non-textured pure nickel. Both aspects depend …

Structural rearrangements governing Johari-Goldstein relaxations in metallic glasses

HB Yu, R Richert, K Samwer - Science advances, 2017 - science.org
The Johari-Goldstein secondary (β) relaxations are an intrinsic feature of supercooled
liquids and glasses. They are crucial to many properties of glassy materials, but the …

Concurrent prediction of metallic glasses' global energy and internal structural heterogeneity by interpretable machine learning

C Liu, Y Wang, Y Wang, M Islam, J Hwang, Y Wang… - Acta Materialia, 2023 - Elsevier
Predicting glasses' properties from their structures is a formidable challenge because of the
inherently disordered atomic configurations. Here we tackle the problem using a new two …

Grain-boundary metastability and its statistical properties

J Han, V Vitek, DJ Srolovitz - Acta Materialia, 2016 - Elsevier
Grain-boundary (GB) structure and properties are usually analyzed in terms of ground-state
(minimum-energy) GB states. However, global equilibrium is rarely achieved in materials. In …

Mechanically-induced grain coarsening in gradient nano-grained copper

W Chen, ZS You, NR Tao, ZH Jin, L Lu - Acta Materialia, 2017 - Elsevier
Gradient nano-grained Cu subjected to tensile tests yields at a stress almost twice of that of
the conventional coarse-grained Cu at or below the room temperature. Beyond the yield …
