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 …

The physics of the colloidal glass transition

GL Hunter, ER Weeks - Reports on progress in physics, 2012 - iopscience.iop.org
As one increases the concentration of a colloidal suspension, the system exhibits a dramatic
increase in viscosity. Beyond a certain concentration, the system is said to be a colloidal …

Connection between mechanical relaxation and equilibration kinetics in a high-entropy metallic glass

YJ Duan, M Nabahat, Y Tong, L Ortiz-Membrado… - Physical review …, 2024 - APS
The slow transition from an out-of-equilibrium glass towards a supercooled liquid is a
complex relaxation phenomenon. In this Letter, we study the correlation between …

Universal aging features in the restructuring of fractal colloidal gels

L Cipelletti, S Manley, RC Ball, DA Weitz - Physical review letters, 2000 - APS
We use multispeckle dynamic light scattering to measure the dynamic structure factor, f (q, τ),
of gels formed by aggregation of colloids. Although the gel is an elastic solid, f (q, τ) nearly …

Atomic-Scale Relaxation Dynamics and Aging in a Metallic Glass Probed<? format?> by X-Ray Photon Correlation Spectroscopy

B Ruta, Y Chushkin, G Monaco, L Cipelletti, E Pineda… - Physical review …, 2012 - APS
We use x-ray photon correlation spectroscopy to investigate the structural relaxation process
in a metallic glass on the atomic length scale. We report evidence for a dynamical crossover …

Aging and rheology in soft materials

SM Fielding, P Sollich, ME Cates - Journal of Rheology, 2000 - pubs.aip.org
We study theoretically the role of aging in the rheology of soft materials. We define several
generalized rheological response functions suited to aging samples (in which time …

Distinct relaxation mechanism at room temperature in metallic glass

YT Sun, R Zhao, DW Ding, YH Liu, HY Bai… - Nature …, 2023 - nature.com
How glasses relax at room temperature is still a great challenge for both experimental and
simulation studies due to the extremely long relaxation time-scale. Here, by employing a …
