Influence of different configurations of Fe nanoparticles on the melting point: a molecular dynamics simulation

The effect of crystallographic orientation of α-Al2O3 on the wetting behavior and adhesion characteristics of aluminum droplets

“…The lower the interfacial potential energy, the more stable the interface is, and the stronger the solid-liquid interface bonding ability is. This is consistent with the views of Wu et al [35].…”

“…The reason for the significant increase in slope in figure 2(a) is that the temperature reaches the melting point. When a solid is heated, the thermal motion of atoms or molecules is enhanced, the rate of diffusion increases, and the solid is gradually transformed into a liquid [35]. From the figure 2(a), it can be seen that there is a sudden change in potential energy in the temperature range of 850-950 K, indicating that the solid aluminum has melted in this temperature range.…”

“…The potential energy or density of the system abruptly changes when the temperature increases during the phase transformation of a solid. By analyzing the change in potential energy at various temperatures, the melting temperature can be determined [35]. The potential energy change curves with temperature during the melting of solid aluminum by the EAM potential are shown in figure 2(a).…”
