Diffusion in rare earth metals

M.P. Dariel, Diffusion in rare earth metals 847 Subject index 877... 

In retrospect, after several years of diffusion studies in rare earth metals, these expectations seem to have been fulfilled. Several of the currently most interesting subjects related to diffusion in metals have been encountered in the course of these studies. Diffusion in rare earth metals is an area far from being exhausted and further fruitful activity in this field of research can be expected. 

Metallic solute diffusion in rare earth metals... 

Diffusion theory in metals, at its present state of art, is not able to provide a quantitative or even qualitative account for the relative values of the solute diffusivities in rare earth metals. The electrostatic interaction theory, which achieved notable success is accounting for the relative diffusivities of various solutes in the noble metals is not applicable to the polyvalent rare earth solvents (Dariel, 1968). Size effects are probably important in determining relative solute...
