WebNational Center for Biotechnology Information WebDopants can be introduced to modify GB energy. When the concentration of the dopant is greater than the solubility limit in the major component, then segregation occurs at GBs. GB mobility is slowed by segregated dopant ions. Concentration of maximum dopant increases with surface to volume ratio of the grain, i.e. it is higher for nanosize grains.
