A Review of Atomistic Scale Studies on Solute Segregation  and Its Mechanism at Grain Boundary

Abstract

Abstract:

By emphatically introducing atomistic scale studies on grain boundary migration and motion mechanism in recent years, the theoretical model, experimental and simulation studies of grain boundary migration mechanism at atomistic scale, and simulation studies of grain boundary motion mechanism at atomistic scale were reviewed. The advantages and disadvantages of these grain boundary evolution mechanisms were discussed. Finally, the future works on grain boundary evolution studies were suggested.

Key words: grain boundary migration, grain boundary motion, atomistic scale
