Molecular dynamics simulations of corrosion resistant alloy Al_3Ni in its solidification

During the hotdip process of the corrosion resistant alloy Al3Ni on the surface of the steel, it involves the solidification from liquid to the coating. It is found that the cooling rate has great influence on the microstructure. By means of molecular dynamics simulation technique, the solidification process of liquid alloy Al3Ni has been performed. The FS Nbody potentials have been adopted to describe the atomic interactions. The structural features have been revealed with the pair distribution. The variation of energy with the temperature and the relationship between the energy and the microstructure has also been studied. It has been concluded that noncrystal occurs at both different cooling rates,however,the degree of order rises slightly at the low cooling rate.
