- The mechanical performance of ultrafine-grained materials is strongly influenced by the lattice defect structure, i.e. the vacancy concentration, the type, arrangement and density of dislocations, the planar fault probability, as well as the amount and character of grain boundaries. In this paper, the correlation between the processing conditions, the lattice defect structure and the plastic behavior of ultrafine-grained materials is overviewed. For the processing route of severe plastic deformation, the influence of applied strain, hydrostatic pressure, as well as melting point, stacking fault energy and alloying on grain size, dislocation density and strength is studied. For nanopowder sintering techniques, the effect of atmosphere, temperature and time of consolidation on lattice defects and mechanical properties is discussed in detail.
