A molecular dynamics simulation of bi-component nanoparticle formation under synchronous electric explosion of Cu and Ni wires was carried out. The approximation of the embedded atom method for a description of the interatomic interactions was used. The simulated nanowires had a cylindrical shape. Periodic boundary conditions were used along the cylinder axis, while in the other directions a free surface was simulated. Heating of the nanowires was performed by scaling of the atomic velocities following a linear law while maintaining a Maxwell distribution. It was shown that as a result of the synchronous electrical dispersion of metal wires the bicomponent nanoparticles having a block structure may be formed. The basic mechanism of particle synthesis was the agglomeration of smaller clusters, and the minor one was the deposition of atoms from the gas phase on the particle surfaces. It was found that the distribution of chemical elements was non-uniform over the cross section of the synthesized particles. The concentration of Cu atoms in the subsurface region was higher than in the particle volume. It was noted that the method of molecular dynamics can effectively be used to select the optimal technological mode of producing nanoparticles with a block structure using electric explosion of metal wires.
