tudnak csatlakozni az előadáshoz Kovács Zsolt Abstract:Multiple 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.
