Nanostructured (NS) materials (grain size d ≤ nm) are currently being intensively investigated. This special attention is due to the distinct physical, mechanical and other properties compared to when they are coarse-grained (CG) [1].Cited by: 9. Nanostructured materials are single-phase or multiphase polycrystalline solids with a typical average grain size of a few nanometers, typically less than nm. Such materials exhibit properties that are substantially different from and are often superior to those of conventional coarse-grained materials, due to their unique microstructure. Nanostructured materials exhibit unique mechanical and physical properties compared with their coarse-grained counterparts, therefore these materials are currently a major focus in materials science. The production methods of nanomaterials affect the lattice defect structure (vacancies, dislocations, disclinations, stacking faults.

Grain boundary (GB) phase transitions can change drastically the properties of nanograined polycrystals, leading to enhanced plasticity or brittleness, increasing diffusion permeability. They influence also liquid-phase and activated sintering, soldering, processing of semi-solid by:   Using asymptotic solution methods of differential equations, the grain-boundary diffusion at transition (between regimes C and B) stages of annealing has been described for nano- and submicrocrystalline materials characterized by nonequilibrium grain boundaries and, thus, by a strong coordinate dependence of the diffusion coefficient near them.

Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle . As this route leads to no residual porosity, it has been recommended for bulk production of nanocrystalline metallic materials. But the grain boundaries in this type of materials are of higher energy, ‘non-equilibrium’ type and even in a material of fixed grain size different properties could be obtained. This calls for property control through grain boundary engineering Cited by:

Grain boundary (GB) diffusion and segregation in nanostructured materials is analysed taking into account the low thermal stability and the large portion of atoms presented in short circuits. To the theory of grain-boundary diffusion in nanostructured materials Article in The Physics of Metals and Metallography (4) April with 12 Reads How we measure 'reads'. The mechanical properties of nanocrystalline materials are reviewed, with emphasis on their con-stitutive response and on the fundamental physical mechanisms. In a brief introduction, the most important synthesis methods are presented. A number of aspects of mechanical behavior are dis-cussed. Nanostructured Materials (NsM) are materials with a microstructure the characteristic length scale of which is on the order of a few (typically 1–10) nanometers. NsM may be in or far away from thermodynamic equilibrium. NsM synthesized by supramolecular chemistry are examples of NsM in thermodynamic by:
