The ratio of the "activation energies" for grainboundary and lattice-diffusion processes is approximately constant for substitutional diffusion in facecentered cubic metals, e.g. the ratio for the selfdiffusion of silver is 0.44. Qn, the "activation energy" for the diffusional process controlling t
