A greater grain boundary
area "produces" more finely dispersed carbides.
25] Te system, a different grain boundary
engineering approach has been tried.
On the other hand, their metallurgical meaning is also highlighted as they quantify significant minera-logical features, like particle composition, grade of locking, degree of contact between phases and grain boundary
curvature and particle pinning in an Al-1mass%Mn alloy.
Because whisker-reinforced ceramic inserts can withstand high temperatures while maintaining strength and hardness, there is an optimum cutting speed--outside the range of carbide tools--where the heat generated lessens the cutting forces by softening the metal and aiding in grain boundary
Stress and texture in titanium thin films, the exoskeleton of the American lobster, and a facet method for grain boundary
plane determination are some other areas explored.
One reason for the decrease is the formation of secondary graphite in the grain boundary
areas during high-temperature heat treatment.

Character in Corrosion Behavior: Linking Atomic Scale Interfacial Structure to Precipitation and Failure Mechanisms," under the direction of Mitra Taheri.
Even in transformations in which classical nucleation theory is thought not to be applicable, for example, recrystallization, grain boundary
sites are often the places at which the transformation originates.

The researchers found that the grain boundary
regions in the individual carbon sheets are magnetically coupled, forming 2-dimensional networks.
