| Abstract: | Based on the embedded atom potential proposed by Mishin, we simulated a solid/liquid coexistence system with 1500 copper atoms by molecular dynamics method. During the process of melting, the solid/liquid interface moves forward layer by layer into the solid phase. According to the collision-limited theory, we obtain the melting temperature of the (001) surface at zero pressure is 1392.9±9.2 K, and the kinetic coefficient is 82.3 cm·s-1·K-1. |
| Keywords: | molecular dynamics thermodynamic melting point embedded atom potential |
