Simulations of liquid transition metals were performed with the use of Johnson’s analytical nearest-neighbor embedded-atom model. The coefficients of self-diffusion for Cu, Ag, Au, Ni, Pd and Pt at their melting points were computed (table 3). The temperature dependence of the self-diffusivity for liquid copper was studied with the value of the activation energy in good agreement with experiments.
