The polymorph selection during rapid solidification of zinc melt was investigated by molecular dynamics simulation. Several methods including g(r), energy, CNS, basic cluster and visualization were used to analyze the results. The results reveal that the cooling rate has no observable effect on the microstructure as T>Tc(Tc is the onset temperature of crystallization); and at the first stage of crystallization, although microstructures are different, the morphologies of nucleus are similar, which are compos...

1 IntroductionPolymorphs have different physical properties[1],e.g.,materials solidified into different polymorphs willresult in different macro-properties.Therefore,controlling polymorph form is crucial for manyapplications,and it is also a great technol
