Project

Reactions of slip dislocations with grain boundary observed by in situ TEM and their relation to slip band structure near grain boundary in bulk (IAA1010702)

results and theoretical calculations indicated that the slip geometry is not the dominant factor. Stresses due to the slip bands formed in one grain and stopped at the GBs and GB dislocation structure are most important. T...
