Abstract
Molecular dynamics simulation of the bicomponent particle formation as a result of simultaneous electric explosion of copper and nickel wires is carried out. The influence of the internal structure of exploding metal wires and the distance between them on the dynamics of their dispersion, the size and phase composition of the formed particles is investigated. It is shown that the basic mechanism of particle synthesis is the agglomeration of smaller clusters, and the minor one is the deposition of atoms from the gas phase on the particle surfaces. The distribution of chemical elements is non-uniform over the cross section of the synthesized particles. The concentration of copper atoms in the subsurface region is higher than in the particle volume. Varying the loading parameters (temperature, distance between the wires) allows controlling the size and phase composition of the synthesized particles
