- The paper investigates the influence of interstitial carbon and oxygen atoms on their diffusion along the , and tilt grain boundaries in face-centered cubic nickel and silver. It is shown that in most cases, the impurity addition leads to the growth in the self-diffusion coefficient along the grain boundaries due to the crystal lattice distortion near the impurity atoms, thereby causing the additional lattice distortion and free volume along the grain boundaries. And the lower the initial free volume on the grain boundary, the stronger is the effect from impurities on the grain boundary diffusion. In this regard, the highest and lowest effects from the impurities are observed for the and tilt grain boundaries, respectively. It is found that the influence of interstitial carbon on the grain boundary diffusion is stronger than that of oxygen.
