Molecular dynamics study of pressure effect on structure and mechanical properties of CuNi alloy

The structure and mechanical properties of CuNi alloy have been investigated by means of molecular dynamic (MD) simulation. The interactions between atoms of the system were calculated by Sutton-Chen type of embedded atom method. The results show that when the sample was cooled down from 2000K to 300K at the cooling rate of 0.01 K/ps, both Ni and Cu atoms are crystallized into face centered cubic (fcc) and the hexagonal close packed (hcp) phases.
