Abstract Diffusion of Ag in nanometer Ni-B amorphous alloy, has been studied by heavy-ion Rutherford backscattering spectroscopy. The values of the diffusion coefficient which were found at 293, 323 and 373K, are 3.5x10-l6, 4.3 x10-l5 and 5.0x10-l4 cm2/s, respectively. Moreover, small values for the activation energy, 0.58 eV, and the pre-exponential factor of the diffusion coefficient, 3.9 x10-16 cm2/s , were derived from Arrhenius plot. Finally, a possible free volume controlled diffusion mechanism was discussed.
