The crystallization of liquid iron nanoparticles has been investigated by means of molecular dynamic (MD) simulation. Simulation result shows that when the liquid samples are cooled from 2500K to 300K at a cooling rate of 0.667K/ps, they are crystallized into body centered cubic (bcc) phase. The transformation to crystalline phase is analyzed through the Common Neighbor Analysis (CNA) methods. The crystallization is carried through two processes: the transformation from liquid to icosahedrons (ico) structure and the transformation from ico to bcc structure. Further, we focus on the size dependence of crystallization of liquid iron.
