THE INFLUENCES OF THE INTERFACIAL MICROSTRUCTRRE ON THE PROPERTIES OF NANOCRYSTALLIINE SOLID MATERIALS

Nanocrystalline materials exhibit remarkable novel proporties comparing with the conventional polycrystallme. It is belleved that the nanocrystailine material is a solid that contains a high density of defect（point defects,dislocations,grain boundaries,interphase boundaries etc.）and a new microstructure that dominate the properties of the materials,In this paper,the spoclal microstructure of nanocrvstailine materials is discussed,and the influences of interfacial microstructrue on properties of nanocrystalline material are also described.
