摘要: AbstractThe basic principles of equilibrium (ES) and non-equilibrium segregation (NES) to boundaries interfaces in solids as a function heat treatment are reviewed. Various models used describe the thermodynamics kinetics both processes outlined an attempt is made emphasise relative merits each models. The importance vacancy-driven effects this kind stressed. Experimental verification sought through discussion amassed data on segregation. Equilibrium NES treated turn critical appraisal light experimental results. section emphasises need for much greater investment currently because only techniques capable measuring fine scale being considered sophisticated expensive methods like. field emission gun scanning electron microscopy, Auger spectroscopy, atom probe ion microscopy.
