Atomic-level structure and structure–property relationship in metallic glasses

YQ Cheng, E Ma - Progress in materials science, 2011 - Elsevier
The structure of metallic glasses (MGs) has been a long-standing mystery. On the one hand,
MGs are amorphous materials with no long-range structural order; on the other hand …

Recent development and application products of bulk glassy alloys

A Inoue, A Takeuchi - Acta Materialia, 2011 - Elsevier
This paper reviews past developments and present understanding of the glass-forming
ability, structure and physical, chemical, mechanical and magnetic properties of bulk glassy …

Three-dimensional atomic packing in amorphous solids with liquid-like structure

Y Yuan, DS Kim, J Zhou, DJ Chang, F Zhu… - Nature materials, 2022 - nature.com
Liquids and solids are two fundamental states of matter. However, our understanding of their
three-dimensional atomic structure is mostly based on physical models. Here we use atomic …

Atomic packing and short-to-medium-range order in metallic glasses

HW Sheng, WK Luo, FM Alamgir, JM Bai, E Ma - Nature, 2006 - nature.com
Unlike the well-defined long-range order that characterizes crystalline metals, the atomic
arrangements in amorphous alloys remain mysterious at present. Despite intense research …

Atomic level structure in multicomponent bulk metallic glass

YQ Cheng, E Ma, HW Sheng - Physical review letters, 2009 - APS
The atomic-level structure of a representative ternary Cu-Zr-Al bulk metallic glass (BMG) has
been resolved. Cu-(and Al-) centered icosahedral clusters are identified as the basic local …

Full icosahedra dominate local order in Cu64Zr34 metallic glass and supercooled liquid

J Ding, YQ Cheng, E Ma - Acta materialia, 2014 - Elsevier
Extensive molecular dynamics simulations were carried out to monitor the development of
icosahedral order in Cu 64 Zr 34 liquid and metallic glass (MG). This study illustrates that at …

Mechanical behavior of metallic glasses: microscopic understanding of strength and ductility

M Chen - Annu. Rev. Mater. Res., 2008 - annualreviews.org
The widespread enthusiasm for research on bulk metallic glasses is driven by both a
fundamental interest in the structure and properties of disordered materials and their unique …

Structural processes that initiate shear localization in metallic glass

AJ Cao, YQ Cheng, E Ma - Acta Materialia, 2009 - Elsevier
For crystalline metals, the structural carriers (dislocations and twins) of plasticity have been
well characterized. In contrast, the structural processes responsible for the localized shear …

The efficient cluster packing model–An atomic structural model for metallic glasses

DB Miracle - Acta materialia, 2006 - Elsevier
A structural model is described for metallic glasses based on a new sphere packing scheme–
the efficient filling of space by solute-centered clusters. This model combines random …

Alloys created between immiscible elements

E Ma - Progress in materials science, 2005 - Elsevier
The development and understanding of alloys is one of the most important themes of
physical metallurgy. Over the past four decades, the progress in modern processing …
