Simulation of the Magnetoplastic Effect in a Cu–Ni Alloy

In this paper, we carry out numerical modeling of the magnetoplastic effect. The molecular-dynamics simulation of deformation processes in Cu–Ni metal alloys are performed, in order to clarify the mechanisms of the magnetoplastic effect, which has been experimentally observed in copper, titanium, aluminum and magnesium alloys. A numerical experiment with tensile deformation of various initial structures under an external magnetic field is carried out. It is shown that the application of a constant magnetic field does not lead to any changes in the structure and velocity of dislocations. However, the obtained results indicate that the application of a constant magnetic field of different magnitudes influences dislocation interactions provided that the dislocation structures contain atoms with different magnetic moments.
