The microstructure of amorphous Al is investigated by molecular dynamics simulation. An unexpected mass effect caused by impurities is observed, which indicated the importance of the mass differences of components in generating the actual structure. Impurities with considerably lower masses than Al give amorphous microstructures, while much larger masses generate quasi-crystalline-like microstructures in the alloy. Both the Voronoi analysis and the pair correlation function are studied to clarify this effect.
