Nanostructured metals and alloys possess ultrahigh strength but suffer from severe shear
instability (strain localization). Recent experiments have shown that the strength and strain …

Amorphous alloys are a new member of the amorphous material family. Due to the lack of
long-range ordering of atomic arrangement, amorphous alloys show unique properties …

Shear band plays a key role in dominating the strength and plasticity of metallic glasses, and
exhibits two kinds of propagation modes under compression, ie, progressive and …

Molecular dynamics simulations on the atomic structure of shear bands (SBs) in Cu 64 Zr 36
metallic glasses are presented. Results show that the atoms in the SB move desultorily, in …

Despite the utmost importance and decades of experimental studies on fatigue in metallic
glasses (MGs), there has been so far little or no atomic-level understanding of the …

Abstract The viscosities of Cu 50 Zr 50 melt from 1250 K to 1435 K were measured in a
containerless electromagnetic levitator under microgravity. The viscosity in the investigated …

Bulk amorphous alloys are in general strong, but brittle. Properly introduced interfaces can
effectively improve their ductility. In this paper, the tensile behavior of amorphous …

In the present work, we show experimental evidence for the dynamic fragile-to-strong (FS)
transition in a series of CuZr (Al) glass-forming liquids (GFLs). A detailed analysis of the …

Mechanical behavior of a Cu-Zr metallic glass (MG) under cyclic indentation loading is
investigated via molecular dynamics simulation. A large-depth indentation after cycling is …

We report that the tensile ductility of metallic glass (MGs) is tunable by introducing gradient
rejuvenated amorphous structures (GRASs) using large-scale atomistic simulations. The …
