Abstract

Interfacial cohesion is determined by the cohesive energy of the interface. Knowing the segregation energies of solute in the interface and on the adjoining free surfaces and mobilities of segregant atoms, the change in cohesive energy of the interface due to solute segregation can be evaluated within the framework of the Langmuir-McLean isotherm. A control of the interfacial cohesion is thus achievable by promoting segregation of the desired solute.
