Abstract: | A molecular dynamics (MD) simulation study has been performed for the rapid solidification of Cu70Ni30 adopting the quantum Sutton-Chen many-body potentials. By analyzing the bond-types and the relation of atomic average energy
versus temperature, it was demonstrated that as cooling rate being 2×1012 K/s, the Cu70Ni30 formed fcc crystal structures and freezing point was found. In addition, having analyzed the transformation of microstructures
and the detail of crystal growth by using atomic trace and visual method, not only could the formation of binary disordered
solid solution be showed, but also the solidification of liquid metals and the crystal growth processes could be, further
understood. |
