Glass formation in binary alloys with different atomic symmetries
Yuan-Chao Hu, Kai Zhang, Sebastian A. Kube +3
Prediction of the glass forming ability (GFA) of alloys remains a major challenge. We are not able to predict the composition dependence of the GFA of even binary alloys. To invest…
Particle rearrangement and softening contributions to the nonlinear mechanical response of glasses
Meng Fan, Kai Zhang, Jan Schroers +2
Amorphous materials such as metallic, polymeric, and colloidal glasses, exhibit complex preparation-dependent mechanical response to applied shear. We perform numerical simulations…
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…
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…
Magnetic alignment of block copolymer microdomains by intrinsic chain anisotropy
Yekaterina Rokhlenko, Kai Zhang, Manesh Gopinadhan +6
We examine the role of intrinsic chain susceptibility anisotropy in magnetic field directed self-assembly of a block copolymer using \textit{in situ} X-ray scattering. Alignment of…
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…
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 …
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…
