Binary And Ternary Systems

Effect of solute interaction on interfacial segregation and grain boundary cohesion is modeled on basis of combined Guttmann and Rice-Wang approaches in binary and ternary systems. It is shown that attractiveIIbinary interaction strengthens interfacial segregation and enhances intergranular embrittlement while repulsion exhibits an opposite effects. In a ternary system the segregation is suppressed by theIJattraction while increased by the repulsion. The effect of the binary interaction is generally stronger compared to the ternary one.
