Despite the continuous and remarkable development of experimental techniques for the investigation of microstructures and the growth of nuclei during the solidificationSolidification of metals, there are still unknown territories around the topic of nucleationNucleation during solidificationSolidification. Such nanoscale phenomena can be effectively observed by means of Molecular DynamicsMolecular Dynamics (MD) simulations which can provide a deep insight into the formation of nuclei and the induced crystal structures. In this study, MD simulations have been performed to investigate the solidificationSolidification of AluminiumAluminium melt and the effects of process parameters such as the cooling rate and hydrostatic pressurePressure on the final properties of the solidified material. A large number of AluminiumAluminium atoms have been used in order to investigate the grain growth over time solidificationSolidification. The population of the Face Centred Cubic (FCC) and amorphous (or non-crystalline) phases has been recorded during the evolution of the process to illustrate the nanoscale mechanisms during solidificationSolidification. Finally, the exothermic nature of the solidificationSolidification process has been effectively captured by measuring the temperature of the Al atoms during grain formation.
