High-entropy induced a glass-to-glass transition in a metallic glass

Nature Communications, 2022
Glass-to-glass transitions can help understanding the glass nature, but it remains difficult to tune metallic glasses into significantly different glass states.

Slow Atomic Motion in Zr-Ti-Cu-Ni-Be Metallic Glasses Studied by NMR [PDF]

, 1998
Nuclear magnetic resonance is used for the first time to detect slow atomic motion in metallic glasses, specifically, Be motion in Zr-Ti-Cu-Ni-Be bulk metallic glasses.

Measuring overlaps in mesoscopic spin glasses via conductance fluctuations [PDF]

, 2007
We consider the electonic transport in a mesoscopic metallic spin glasses. We show that the distribution of overlaps between spin configurations can be inferred from the reduction of the conductance fluctuations by the magnetic impurities.

Simulation of Cu-Mg metallic glass: Thermodynamics and Structure [PDF]

, 2003
We have obtained effective medium theory (EMT) interatomic potential parameters suitable for studying Cu-Mg metallic glasses. We present thermodynamic and structural results from simulations of such glasses over a range of compositions.

Plastic Dynamical Model for Bulk Metallic Glasses

Complexity, 2019
Based on previous experimental results of the plastic dynamic analysis of metallic glasses upon compressive loading, a dynamical model is proposed. This model includes the sliding speed of shear bands in the plastically strained metallic glasses, the ...

Improve the Forming Ability of Al-Based Metallic Glass Under Ultrasonic Vibration at Room Temperature

Frontiers in Materials, 2021
In this work, a rapid and controllable ultrasonic vibration method for forming Al-based metallic glass at room temperature is proposed. This method can dramatically improve the forming ability of Al-based metallic glasses, which are virtually brittle at ...

Ultrastable metallic glasses formed on cold substrates

Nature Communications, 2018
Producing ultrastable metallic glasses has always been associated with substrates heated close to the glass transition temperature. Here, the authors show that reducing the deposition rate of the metallic glass on a cold substrate produces ultrastable ...

Phonon dispersion relation of metallic glasses [PDF]

, 2016
Experimental data on the phase sound speed of metallic glasses show anomalies in the terahertz range, reflecting an underlying complex behavior of their phonon dispersion spectrum not yet explained.

Thermodynamics and kinetics of the Mg65Cu25Y10 bulk metallic glass forming liquid [PDF]

, 1998
The thermodynamics and kinetics of the bulk metallic glass forming Mg65Cu25Y10 liquid were investigated using differential scanning calorimetry and three-point beam bending. The experiments lead to the determination of the thermodynamic functions as well

Structure and Radiation Damage of Metallic Glasses

Успехи физики металлов, 2002
Two most known models of metallic-glass structure — the model of random closepacked spheres and the polycluster model — are considered. Peculiarities of the structure defects of glasses possessing these structures are compared.
