Abstract
The features of grain boundary disclination splitting in nanocrystals are theoretically examined. It is shown that there are three basic var iants of such splitting as a relaxation process which are specified by different values of elastic-energy decrease. Also, the contribution o f disclinations as strengthening elements to processes of plastic defo rmation in metallic glass-nanocrystal composites is discussed.
