Abstract

The crystallization process of a aluminium (Al) amorphous mono-atomic with 2048 atoms is studied with molecular dynamics (MD) simulation. Amorphous and crystal structure of Al is reproduced by applying fast cooling treatment and crystal behaviour from amorphous phase by means of MD simulation. The local order of the system have been analysed by bond orientational order parameters, the radial distribution functions and atomic coordinates. The simulation results also show that there are transformations from a disordered structure to a stable crystal phase during the crystallization.
