AbstractThe understanding of deformation mechanisms operating in nanocrystalline (nc) materials is very important in order to understand and improve their mechanical properties, and it is necessary for the scientifically motivated design of new materials. The present thesis investigates the fundamentals of plastic deformation of fully dense bulk nanocrystalline f.c.c metals, such as Pd and Pd alloys with a grain size as small as 15 nm. Shown results were a first systematic analysis of mechanical response and microstructure of nc materials which had been performed in a wide range of strains and at different strain rates. It was demonstrated that fully dense nanocrystalline pure noble metal exhibits the highest strength ever achieved for noble metals. Careful investigation of microstructure by transmission electron microscopy revealed that nc materials deform by grain boundary sliding, grain rotation, twinning, dislocation slip.dc.description.abstract
