Résumé
In this paper, based on the embedded atom method (EAM) potential, molecular dynamics simulations of the solidification process of Al-4 at.%Cu alloy is carried out. The Al-Cu alloy melt is placed at different temperatures for isothermal solidification, and each stage of the entire solidification process is tracked, including homogeneous nucleation, nucleus growth, grain coarsening and microstructure evolution. In the nucleation stage, the transition from high temperature to low temperature manifests a change from spontaneous nucleation mode to divergent nucleation mode. The critical nucleation temperature of the Al-Cu alloy is determined to be about 0.42
