Thermochemical Interactions Versus Site Competition in Grain Boundary Segregation and Embrittlement in Multicomponent Systems
Résumé
Several elementary mechanisms play a role in intergranular segregation and embrittlement in multi-component systems : site competition, attractive and repulsive chemical interactions. The physical significance of these interactions, their thermodynamic modeling and validity, and the experimental evidence available for each of them are discussed with particular emphasis on Fe-base alloys with metallic and non-metallic segregating solutes.
