Mechanical properties of ultra fine grained copper prepared by particulate processing and bulk deformation processing were studied. Specimens were prepared by (i) consolidation of nanocrystalline particles produced by solution phase synthesis (SPS) and POLYOL processes and (ii) severe plastic deformation (SPD) by equal channel angular extrusion (ECAE). The mechanical properties were determined by micro hardness measurements, compression testing, and three-point bend testing. Whereas the particulate processed copper exhibited high hardness values, the specimens failed without exhibiting any plastic deformation in 3-point bend tests.
