Abstract: Molecular dynamics method was applied to simulate processes of melting of disordered CuAg alloy particles in the D = 3 – 5 nm size range. It is shown that for small nanoparticles (diameter D = 3 nm) melting process is associated with formation of an outer layer consisting of Ag atoms and further transition of the particle to an amorphous state. With increasing the particle size to D = 5 nm, this effect was not observed.
Keywords: computer simulation, molecular dynamics, CuAg nanoalloy.
