Entropy-dominated grain boundary segregation
The phenomenon of entropy-dominated grain boundary segregation is introduced and discussed. Numerous examples of the grain boundaries and solutes exhibiting this phenomenon are compiled and predicted for example of alpha-iron-based alloys and other host materials. Consequences of entropy-dominated grain boundary segregation for grain size stabilization and intergranular embrittlement are shown. [GRAPHICS] .
