The deformation and flow of disordered solids, such as metallic glasses and concentrated
emulsions, involves swift localized rearrangements of particles that induce a long-range …

Abstract High-entropy alloys (HEAs), as a new class of materials, are nearly equiatomic and
multi-element systems, which can crystallize as a single phase or multi-phases. Most of the …

Shear-banding is a ubiquitous plastic-deformation mode in materials. In metallic glasses,
shear bands are particularly important as they play the decisive role in controlling plasticity …

Serration and noise behaviors in plastically deforming solids are related to avalanches of
deformation processes. In the stress-strain curves, the serration characteristics are visible as …

The future of metallic glasses as an advanced structural and functional material will to a
great extent depend on the understanding and control of their mesoscopic flow defects …

High-entropy alloys (HEAs) are a novel class of alloys that have many desirable properties.
The serrated flow that occurs in high-entropy alloys during mechanical deformation is an …

Lacking of plasticity at ambient temperature severely hinders the wide applications of bulk
metallic glasses, and a significant challenge is to improve the plasticity. Based on the …

In this study, shear-band propagation during serrated and non-serrated flow of a bulk
metallic Zr52. 2Ti5Cu17. 9Ni14. 6Al10 (Vit105) glass was investigated. It was found that …

A serrated flow, which occurs in a material undergoing mechanical deformation, is a
complex process of great engineering significance. Here statistical, dynamical, and …

A Zr-based bulk metallic glass produced using selective laser melting (SLM) was compared
to the same alloy fabricated using traditional suction-casting. Analysis of the fracture …
