Structural Nanocrystalline Materials
2007Nanocrystalline materials exhibit exceptional mechanical properties, representing an exciting new class of structural materials for technological applications. The advancement of this important field depends on the development of new fabrication methods, and an appreciation of the underlying nano-scale and interface effects.

Magnetism of nanocrystalline materials
Hyperfine Interactions, 1990Nanocrystalline solids are materials consisting of small crystallites (typically 1–10 nanometers). These materials have a high proportion of atoms located in the interfacial regions between the crystallites. Therefore their magnetic properties are strongly determined by the interfaces.

Twinning in nanocrystalline materials
Physics Letters A, 2012Abstract The deformation twinning of nanocrystalline materials is analyzed within the dislocation theory of twins. This approach is used for the description of the recently observed inverse grain size effect in nanocrystalline face-centered-cubic metals.

Diffusion in nanocrystalline material
Solid State Communications, 1987Abstract The paper reports on first investigations of the diffusion in nanocrystalline materials. The self-diffusion of the radioisotope 67Cu in nanocrystalline copper has been measured by serial sectioning with the aid of ion-beam sputtering. The values of the diffusion coefficients which were found at 353 K and 393 K are 2×10−18 m2/s and 1.7×10−17 ...

Quasi-nanocrystalline materials
Nanostructured Materials, 1997Abstract Quasi-nanocrystalline materials (nanostructured polycrystals with quasi-periodic grain boundaries) are defined as new-types of nanostructured materials. The specific role of quasi-periodic boundaries in plastic deformation in nanostructured polycrystals is theoretically examined.

Mechanosynthesis of nanocrystalline materials
Hyperfine Interactions, 1994Mechanical alloying is a method of synthesis of advanced materials, often with non-equilibrium structures, and, remarkably, of crystalline materials with nanometersized grains. Grinding is also a way of inducing or activating chemical reactions. After having described some general characteristics and some applications of high-energy ball-milling, we ...

Stability Map for Nanocrystalline and Amorphous Materials
Physical Review Letters, 2008We present a stability map which predicts the domains of shear instability due to grain rotation in nanocrystalline materials. The onset of this mode of instability is influenced by grain-size-dependent mechanisms and the length-scale of intergranular interaction.
