摘要: Structural models, and geometric criteria for ‘special’ grain boundary triple junction properties are presented assessed on the basis of experimental studies energetic, kinetic, physical, chemical, mechanical phenomena; applicability these shown to be due their importance in defining intercrystalline dislocation structures. Methods controlling distribution, quantity structure boundaries polycrystalline materials also presented. Several unusual exhibited by nanocrystalline simply a manifestation an enhanced volume fraction consisting distinct line disclination
