Abstract

Diffusion phenomena are widely involved in many metallurgical transformations and processes and are frequently mentioned throughout the present work. This chapter treats the basic laws of diffusion Before going on to describe three typical cases where its effects are clearly visible in the microstructure, corresponding to atomic transfer at an interface between (1) two solids (depleted zone formation); (2) a solid and a gas (case hardening); (3) a solid and a liquid (galvanising). These three examples all have important practical consequences.
