Lecture

Diffusion in Alloys: Diluted and Binary Alloys

Description

This lecture covers the calculation of diffusion in alloys, including diluted and binary alloys, chemical diffusion, phase separation, and the effects of concentration on intermolecular forces. It also discusses the impact of solute addition on self-diffusion, the concept of intrinsic diffusion coefficient, and the thermodynamic factors influencing diffusion. The lecture further explores the free energy of mixing, phase separation in materials, and the formation of two-phase systems in binary alloys. Additionally, it delves into the mechanisms of spinodal decomposition and germination and growth in phase separation. The lecture concludes with examples of phase separation in lipid mixtures and the diffusion of bath water into the skin.
