Influence of icosahedral order on the second peak splitting of pair distribution function for Mg70Zn30 metallic glass
Yongchao Liang,Rang-su Liu,Yunfei Mo,Hairong Liu,Zean Tian,Qun-yi Zhou,Hai-Tao Zhang,Hai-Tao Zhang,Li-li Zhou,Zhao-Yang Hou,Ping Peng +10 more
TL;DR: In this paper, the second peak splitting in pair distribution function (PDF) g (r ) curve of Mg 70 Zn 30 metallic glass is mainly caused by the intercross-shared (IS) cluster linked of two icosahedra.

Cooling rate dependence of polymorph selection during rapid solidification of liquid metal zinc
TL;DR: In this article, the polymorph selection during rapid solidification of zinc melt was investigated by molecular dynamics simulation, and the results reveal that the cooling rate has no observable effect on the microstructure as T > T c (T c is the onset temperature of crystallization); and at the first stage, although microstructures are different, the morphologies of nucleus are similar, which are composed of HCP and FCC layers.

Molecular dynamics study of melting and freezing of small Lennard-Jones clusters
TL;DR: In this paper, the properties of small clusters of Lennard-Jones atoms were studied by using molecular dynamics simulations, and it was found that these clusters undergo a transition, analogous to a melting transition for bulk materials, from a low-energy solidlike structure at low temperatures to a set of higher energy liquidlike structures at high temperatures.
