Summary:The consolidation process of agglomerated Cu – γ-Al2O3 composite nanopowder was investigated experimentally. Process includes powder compacting by uniaxial cold pressing, sintering in hydrogen atmosphere, and hot extrusion. The interdependence of alumina content, powder agglomeration, green density of compacts, and isothermal sintering behavior of powders was evaluated.
