Abstract

Nanomaterials generally exhibit drastically different properties compared to their bulk counter part having the same composition. The well-known dependence of the yield stress of materials on the grain size nanometric materials means that other mechanical proeperties are also significantly influnced by size. Much evidence indicates that the earlier assumptions are experimentally verified, namely, that at the initial stages low temperature (T < 300 K) annealed polycrystals plastically deform by grain boundary sliding on separate facets; actually GB microsliding, leading to stress concentration and generation of dislocations from areas where GB microsliding occurs.
