The influence of the number of atoms, N = 3000, 5000, 7000, and 9000 atoms, at temperature T = 300 K and temperatures T = 300, 500, 700, 900, 1100, 1300, and 1500 K at N = 9000 atoms, on microscopic structure, phase transition temperature, and mechanical property of bulk aluminium in an amorphous state is studied by the molecular dynamics method with the Sutton–Chen embedded interaction potential and the periodic boundary condition. Structural results are analyzed through the radial distribution function, the total energy of the system, the size, and the common neighbor analysis. The phase transition temperature is determined by the relationship between the total energy of the system and temperature. The mechanical property is derived from the deformation along the Z-axis. It can be noted that when the number of atoms increases, the first peak’s position for radial distribution function changes, the first peak’s height decreases, the number of FCC and HCP structural units decreases, the number of Amor structural units increases, and the total energy of system increases. It can be seen that when temperature increases, the first peak’s position changes, the first peak’s height decreases, the number of FCC and HCP structural units decreases, the number of Amor structural units increases, and the total energy of the system decreases. The obtained results are very useful for experimental studies in the future.
