First-principles study of carbon segregation in bcc iron symmetrical tilt grain boundaries

Segregation of light elements can profoundly affect the energies and cohesive properties of grain boundaries. First-principles calculations have been performed to determine the carbon solution energies and cohesive properties of three different grain boundaries in presence of carbon. It is demonstra...
