    Abstract:

    Multiple studies in recent years have proven severe plastic deformation (SPD) techniques as a very efficient way to produce nanostructured metals and alloys with significantly improved mechanical and functional properties, with the latter affected by several factors, including ultrafine grains and also the atomic structure of boundaries in resulting nanomaterials [1,2]. 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 materials with superior multifunctional properties [3,4], 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 placed on the physical nature and the use of multifunctional nanomaterials for their innovative applications in medicine and engineering.
