Molecular Dynamics Modeling of the Long-Range Effect in Metals upon Irradiation with Copper Nanoclusters (Cu141)

Abstract

Molecular dynamics modeling of the long-range effect in a metal target irradiated with nanoclusters is performed. It is found that moving high-temperature regions merge in the bulk of the target when it is subjected to simultaneous irradiation with several nanoclusters having different areas of interaction with its surface. The temperature in the region of merger risse abruptly and goes past the melting temperature of the target. This can produce structural changes in the crystal lattice at depths inside the target exceeding that of nanocluster penetration, resulting in the long-range effect.
