Dynamic relaxation is an intrinsic and universal feature of glasses and enables fluctuation
and dissipation to occur, which induces plentiful behaviour, maintains equilibrium, and …

The intrinsic structural heterogeneities of amorphous alloys are closely related to the
thermodynamics and dynamical behavior, such as relaxation/crystallization, glass transition …

Introducing regions of looser atomic packing in bulk metallic glasses (BMGs) was reported to
facilitate plastic deformation, rendering BMGs more ductile at room temperature. Here, we …

非晶合金弛豫/晶化, 玻璃转变, 塑性变形等热力学和动力学行为都与其固有的结构非均匀性密切
相关. 但是, 由于淹没在亚稳的长程无序结构中, 探究非晶合金的结构非均匀性十分困难. 尤其 …

In a crystalline material, structural defects such as dislocations or twins are well defined and
largely determine the mechanical and other properties of the material. For metallic glass …

Plastic deformation and relaxation dynamics are two major topics in glass physics.
Secondary (β) relaxation has been assumed to be a relevant plastic mechanism in …

Quantitative density measurements from electron scattering show that shear bands in
deformed Al 88 Y 7 Fe 5 metallic glass exhibit alternating high and low density regions …

Plastic deformation of metallic glasses (MGs) has long been considered to be confined to
nanoscale shear bands, but recently an affected zone around the shear band was found …

The strength-ductility paradox in structural materials remains a long-standing dilemma in
advanced materials synthesis. Metallic glasses (MGs) that are structural materials of …

The local energy dissipation near the shear band plane was characterized by using a
method of amplitude-modulation atomic force microscope, in a Cu 50 Zr 50 metallic glass …
