Spectral descriptors for bulk metallic glasses based on the thermodynamics of competing crystalline phases
Eric Perim, Dongwoo Lee, Yanhui Liu +8
Metallic glasses have attracted considerable interest in recent years due to their unique combination of superb properties and processability. Predicting bulk metallic glass former…
The effects of cooling rate on particle rearrangement statistics: Rapidly cooled glasses are more ductile and less reversible
Meng Fan, Minglei Wang, Kai Zhang +4
Amorphous solids, such as metallic, polymeric, and colloidal glasses, display complex spatiotemporal response to applied deformations. In contrast to crystalline solids, during loa…
Predicting Bulk Metallic Glass Forming Ability with the Thermodynamic Density of Competing Crystalline States
Eric Perim, Dongwoo Lee, Yanhui Liu +8
Despite two decades of studies, the formation of metallic glasses, very promising systems for industrial applications, still remains mostly unexplained. This lack of knowledge hind…
Beyond packing of hard spheres: The effects of core softness, non-additivity, intermediate-range repulsion, and many-body interactions on the glass-forming ability of bulk metallic glasses
Kai Zhang, Meng Fan, Yanhui Liu +3
When a liquid is cooled well below its melting temperature at a rate that exceeds the critical cooling rate , the crystalline state is bypassed and an amorphous glassy state f…
On the origin of multi-component bulk metallic glasses: Atomic size mismatches and de-mixing
K. Zhang, B. Dice, Y. Liu +3
The critical cooling rate , below which liquids crystallize upon cooling, characterizes the glass-forming ability (GFA) of the system. While pure metals are typicall…
Asymmetric crystallization during cooling and heating in model glass-forming systems
Minglei Wang, Kai Zhang, Zhusong Li +4
We perform molecular dynamics (MD) simulations of the crystallization process in binary Lennard-Jones systems during heating and cooling to investigate atomic-scale crystallization…
The glass-forming ability of model metal-metalloid alloys
Kai Zhang, Yanhui Liu, Jan Schroers +2
Bulk metallic glasses (BMGs) are amorphous alloys with desirable mechanical properties and processing capabilities. To date, the design of new BMGs has largely employed empirical r…
Shear accelerated crystallization in a supercooled atomic liquid
Zhen Shao, Jonathan P. Singer, Yanhui Liu +6
A bulk metallic glass forming alloy is subjected to shear flow in its supercooled state by compression of a short rod to produce a flat disc. The resulting material exhibits enhanc…
Can the packing efficiency of binary hard spheres explain the glass-forming ability of bulk metallic glasses?
Kai Zhang, W. Wendell Smith, Minglei Wang +4
We perform molecular dynamics simulations to compress binary hard spheres into jammed packings as a function of the compression rate , size ratio , and number fraction …
Ultrastrong and Ultrastable Metallic Glass
Daisman P. B. Aji, Akihiko Hirata, Fan Zhu +7
The lack of thermal stability, originating from their metastable nature, has been one of the paramount obstacles that hinder the wide range of applications of metallic glasses. We…
Computational studies of the glass-forming ability of model bulk metallic glasses
Kai Zhang, Minglei Wang, Stefanos Papanikolaou +4
Bulk metallic glasses (BMGs) are produced by rapidly thermally quenching supercooled liquid metal alloys below the glass transition temperature at rates much faster than the critic…
