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.
