Diffusion in Alloys

This lecture covers the diffusion phenomena in alloys, focusing on phase separation, phase diagrams, and diffusion at interfaces. It explains the composition profiles in binary alloys, diffusion in stainless steel, and the formation of grain boundaries. The lecture also delves into the movement of dislocations, shear stress, and slip planes in metals, emphasizing the factors influencing dislocation motion. Additionally, it discusses chemical diffusion in ionic crystals, mutual diffusion between different species, and the Nernst-Planck equation. The presentation concludes with an exploration of nickel oxidation, void nucleation, and the growth of nanocrystalline structures.
