Abstract
A simple phenomenological model of solute segregation at partially ordered grain boundaries is proposed. It is consistent with present understanding of equilibrium segregation phenomena. The model is used to correlate complex concentration and temperature dependences of silicon segregation in ordered Fe–Si alloys. It also offers a new interpretation of boron segregation in FeAl base intermetallics as well as interesting consequences of nickel segregation in ordered NiAl solid solutions.
