Wave vector dependence of the dynamics in supercooled metallic liquids
B. Ruta, S. Hechler, N. Neuber +13
We present a detailed investigation of the wave vector dependence of collective atomic motion in Au49Cu26.9Si16.3Ag5.5Pd2.3 and Pd42.5Cu27Ni9.5P21 supercooled liquids close to the…
Possible origin of -relaxation in amorphous metal alloys from atomic-mass differences of the constituents
Bingyu Cui, Zach Evenson, Beibei Fan +3
We employ an atomic-scale theory within the framework of nonaffine lattice dynamics to uncover the origin of the Johari-Goldstein (JG) -relaxation in metallic glasses (MGs). Com…
Breakdown of the Stokes-Einstein Relation Above the Melting Temperature in a Liquid Phase-Change Material
Shuai Wei, Zach Evenson, Moritz Stolpe +2
The dynamic properties of liquid phase-change materials (PCMs), such as viscosity and atomic self-diffusion coefficients D, play an essential role in ultrafast phase switching…
Activation energy spectrum for relaxation and polyamorphism in an ultra-viscous metallic glass former
Isabella Gallino, Daniele Cangialosi, Zach Evenson +4
Many glass-formers exhibit phase transitions between two distinct liquid states. For some metallic glass-formers, the liquid-liquid transition is experimentally found in the superc…
Liquid-liquid transition revealed by quasi-static cooling of an ultra-viscous metallic liquid
S. Hechler, B. Ruta, M. Stolpe +7
Temperature-driven polyamorphism has been reported in various supercooled liquids and glasses. The dynamical and structural routes followed by the system during such crossovers are…
X-Ray Photon Correlation Spectroscopy Reveals Intermittent Aging Dynamics in a Metallic Glass
Zach Evenson, Beatrice Ruta, Simon Hechler +4
We use coherent X-rays to probe the aging dynamics of a metallic glass directly on the atomic level. Contrary to the common assumption of a steady slowing down of the dynamics usua…
