Quenched-in liquid in glass

Materials Futures, 2023
Glasses have long been considered as frozen liquids because of the similarity between their static amorphous structures. While the modern theories about glass transition suggest that glass transition may result from supercooling of a heterogeneous liquid

Investigation of Thermophysical Properties of Zr-Based Metallic Glass-Polymer Composite

Metals, 2021
Composites based on Zr65Cu17.5Ni10Al7.5 metallic glass (MG) and polytetrafluoroethylene (PTFE) were prepared by ball milling. Different composites (30/70, 50/50 and 70/30) were produced.

Thermoplastic Forming of a Hydrophilic Surface with a Nanostructure Array on Zr-Cu-Ni-Al-Y Bulk Metallic Glass

Metals, 2021
The poor thermoplastic formability of reactive Zr-based bulk metallic glass becomes the main limiting factor for replacing the noble-metal-based and Be-rich bulk metallic glasses in nanostructure fabrication.
