CuNi alloy

The mechanical properties of polycrystalline Cu70Ni30 sample was simulated by Molecular dynamics (MD) simulations. The interaction potential used in the calculations for interactions between atoms in the sample is the Quantum Sutton-Chen embedded potential. This sample at temperature of 300 K consists of the face-centered cubic (fcc), hexagonal closest packed (hcp) structures and few disordered structures.

At a temperature of 300 K, both Ni and Cu atoms are crystallized into the face-centered cubic (FCC) and the hexagonal close-packed (HCP) phases, respectively. The mechanical characteristics of the sample at 300 K were also analyzed in detail through the determination of elastic modulus, number of atoms, and void distribution during the tensile process.

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.

The influence of the size of Cu precipitates on the mechanical properties of steel was studied by Finite Element Method. The results indicated that the strength of the matrix (strength of matrix) first increased then decreased with the increasing size of Cu-rich clusters. Cu content affects the structural and mechanical changes of these alloys. However, the mechanism of influence of Cu content on the structural and mechanical properties of CuNi alloy at different pressures has not been clarified.
