Abstract: In this paper a molecular-dynamic study of melting of binary metal nanowires with different initial composition and mesoscopic structure is carried out. For the Ni – Cu system it is shown that the melting temperature is significantly affected not only by the percentage of components, but also by their location in the particle, i.e. by the mesoscopic structure. Thus, the Ni nanowire coated with Cu atoms retains its stability at much higher temperatures than the Cu nanowire coated with Ni atoms, ceteris paribus.
Keywords: metal nanowire, Ni – Cu system, melting, size dependence, molecular dynamics.
