Molecular dynamics simulation technique was applied to investigate the melting point of aluminium. Semi-empirical potentials, based upon the embedded atom method were employed to calculate lattice parameter, energy per atom and mean square displacements. Melting temperature was found to compare well with the experimental results. Computer simulation studies of some low index (111), (113) and (112) twin boundaries at various temperatures and their effect on the melting temperature were also carried out. It was observed here that in the presence of twin boundaries, aluminium melts at lower temperatures, as compared to normal melting point.
