Hot Extrusion process is performed on aluminum powder compacts reinforced with copper wires, 1, 2, 3 and 4 wires. The temperatures selected for extrusion process are below recrystallization temperature 350°C and over 450°C. Graphite lubricate is used as it is good lubricate when works in elevated temperatures. The process gives observable enhancement in both density and strength. The consolidation density reached nearly to 98% of the theoretical one, especially for specimen extruded at 450°C. The flow behavior of reinforced wires differs from that of green aluminum due to change in thermal conductivity.
