Interactions between point defects and grain boundaries: segregation
The real grain boundary - Effects of temperature and chemistry

Segregation at grain boundaries results from the redistribution of solute (controlled addition or impurity) between crystals and boundaries during thermal or thermomechanical processing. For any polycrystalline material, solute enrichment at the joints has important consequences on structural and functional properties: brittleness or consolidation, intergranular corrosion, intergranular slippage, modification of electrical properties, etc. For comprehensive documentation on segregation, readers may refer to .
