Heterodiffusion in Metals

This lecture covers the concept of heterodiffusion in metals, focusing on examples of metals with solutes at infinite dilution and their correlation with the valence of the solvent-solute. It also discusses interstitial solutes such as C, N, O and the effect of temperature on the activation energy of direct interstitial diffusion. The presentation delves into diffusion mechanisms in solids, including self-diffusion in metals, diffusion in compound alloys, and the diffusion of electrolytes in liquids.
