ultiple studies in recent years have proved severe plastic deformation (SPD) techniques as a very efficient way
to produce nanostructured metals and alloys with significantly improved mechanical and functional properties,
the latter affected by several factors, including ultrafine grains and also the atomic structure of boundaries in resulting
nanomaterials. This report presents the results of complex studies of the formation of different grain boundaries (low
angle and high angle ones, special and random, equilibrium and non-equilibrium with strain-distorted structure as well
as with the presence of grain boundary segregations and precipitations) in nanostructured materials processed using SPD
with various regimes and routes. This entails the materials with superior multifunctional properties, i.e., the combination
of high mechanical and functional properties (corrosion and radiation resistance, electrical conductivity, etc.) that are
induced by grain boundary design. Particular emphasis is laid on the physical nature and the use of multifunctional
nanomaterials for their innovative applications in medicine and engineering.
