Recent Advances in Metallic Glasses
Silvia Bonfanti, Ralf Busch, Jesper Byggmästar +12
This paper reviews recent advances in the field of metallic glasses, focusing on the development of novel experimental techniques and in silico models. We discuss progress in exper…
Emergence of multiple relaxation processes during low to high density transition in Au49Cu26.9Si16.3Ag5.5Pd2.3 metallic glass
Alberto Ronca, Antoine Cornet, Jie Shen +8
The existence of multiple amorphous states, or polyamorphism, remains one of the most debated phenomena in disordered matter, particularly regarding its microscopic origin and impa…
Break-down of the relationship between α-relaxation and equilibration in hydrostatically compressed metallic glasses
Antoine Cornet, Jie Shen, Alberto Ronca +20
Glasses encode the memory of any thermo-mechanical treatment applied to them. This ability is associated to the existence of a myriad of metastable amorphous states which can be pr…
On the interplay of liquid-like and stress-driven dynamics in a metallic glass former observed by temperature scanning XPCS
Maximilian Frey, Nico Neuber, Sascha Sebastian Riegler +16
Modern detector technology and highly brilliant fourth-generation synchrotrons allow to improve the temporal resolution in time-resolved diffraction studies. Profiting from this, w…
Denser glasses relax faster: a competition between rejuvenation and aging during in-situ high pressure compression at the atomic scale
A. Cornet, G. Garbarino, F. Zontone +15
A fascinating feature of metallic glasses is their ability to explore different configurations under mechanical deformations. This effect is usually observed through macroscopic ob…
Disentangling structural and kinetic components of the α-relaxation in supercooled metallic liquids
Nico Neuber, Oliver Gross, Maximilian Frey +10
The particle motion associated to the α-relaxation in supercooled liquids is still challenging scientists due to its difficulty to be probed experimentally. By combining synchrotro…
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…
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…
Thermodynamics, kinetics and fragility of bulk metallic glass forming liquids
Ralf Busch, Zach Evenson, Isabella Gallino +1
This review deals with the kinetic and thermodynamic fragility of bulk metallic glass forming liquids. The experimental methods to determine the kinetic fragility, relaxation behav…
Glass transition with decreasing correlation length during cooling of Fe50Co50 superlattice and strong liquids
Shuai Wei, Isabella Gallino, Ralf Busch +1
The glass transition GT is usually thought of as a structural arrest that occurs during the cooling of a liquid, or sometimes a plastic crystal, trapping a metastable state of the…
