The rapidly cooling processes of Cu were investigated using molecular dynamics simulations based on Mei's embedded atom model. The atomic transport properties in the liquid and amorphous states were studied. The diffusion movement in amorphous Cu near Tg showed similar behavior as that in supercooled liquids at low temperature. The pair correlation function and the pair analysis technique were used to describe the complex microstructural evolutions during the rapidly cooling processes and the long relaxation processes. The results show that the crystallization of amorphous Cu was caused by the atomic diffusion.
