Ultrastable Metallic Glass

open access: yesAdvanced Materials, 2013
A new metallic glass, which was created by vapour deposition at an appropriately high substrate temperature, shows exceptional thermal stability, and enhanced glass transition temperature and elastic modulus. Comparing this new material with other organic glasses prepared by similar routes and known as ultrastable glasses demonstrates the formation of ...

Plastic Dynamical Model for Bulk Metallic Glasses

open access: yesComplexity, 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

open access: yesFrontiers 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

open access: yesNature 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 ...

Review of Thermoplastic Drawing with Bulk Metallic Glasses

open access: yesMetals, 2022
This study summarizes the recent progress in thermoplastic drawing of bulk metallic glasses. The integration of drawing with templated embossing enables the fabrication of arrays of high-aspect-ratio nanostructures whereas the earlier drawing ...

Structure and Radiation Damage of Metallic Glasses

open access: yesУспехи 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.

Excellent glass forming ability and plasticity in high entropy Zr20Ti20Hf20M20Be20 (M = Cu, Ni, Co) alloys

open access: yesResults in Physics, 2018
We reported here the studies of a series of Zr20Ti20Hf20M20Be20 (M = Cu, Ni and Co) quinary high entropy bulk metallic glasses. Glasses with critical diameters (Dc) of 3 mm, 8 mm and 5 mm, respectively has been successfully fabricated by copper mold ...

Two-way tuning of structural order in metallic glasses

open access: yesNature Communications, 2020
While metallic glasses are expected to have tunable structures, these have rarely been demonstrated. Here, the authors combine temperature and pressure to show a two-way structural tuning in rare earth-based metallic glasses beyond the nearest-neighbor ...

Improving plasticity of metallic glass by electropulsing-assisted surface severe plastic deformation

open access: yesMaterials & Design, 2019
Using either electropulsing (EP) or surface severe plastic deformation (SSPD) to process metallic glasses can improve their plasticity, however, the moderate improvement in plasticity does not warrant a commercial usage.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.
