Outline of Final Research Achievements

The aim of this group is to produce bulk nanostructured metals using various forms of processing methods. One form makes use of severe plastic deformation (SPD) and the other of electrodeposition (ED). We investigate mechanisms how nanostructured grains are attained by SPD and compare with the mechanical and functional properties with those produced by ED to examine how the processing procedures affect the resultant properties. Our group has also an important task to provide the nanostructured materials to other groups so that it is possible to correlate between microstructural states and their properties.
