Transition-metal and rare-earth diffusion coefficients were determined at 1323K, by means of field emission energy dispersive spectroscopic analysis of diffusion couples. Estimates of the mutual interdiffusion coefficients were deduced by preparing arc-melted and annealed polycrystalline specimens. It was assumed that the diffusion coefficients were independent of concentration. The results indicated that the diffusion coefficient of Dy was 2.9 x 10-12cm2/s.
