Explain Fick’s diffusion laws.
Diffusion is the process by which atoms or molecules migrate from regions of higher concentration to regions of lower concentration due to random thermal motion. In materials science, diffusion is fundamental to processes such as alloying, heat treatment, sintering, oxidation, and phase transformations. Fick’s diffusion laws provide a quantitative description of diffusion behavior in solids. Fick’s first law describes steady-state diffusion, where the concentration profile does not __________ ___ _____ _________ _________ _______ ________ ___ _____.
