The diffusion of 67Ga radiotracer in polycrystals of Ni3Ga intermetallic was studied by residual activity method. Both volume- and grain boundary diffusivity was investigated and quantitatively described. Obtained diffusivites of Ga in Ni3Ga lattice show the increasing dependence on increasing Ga concentration.
