... grain boundaries and the adjacent areas become depleted of solute. There is direct experimental evidence for both of these mechanisms. Special heat treatments are used to minimize the formation of PFZs. Precipitate-free zones can be eliminated by a two-stage heat treatment where nucleation is induced...
