Abstract | ||
The present work concerns with study of extrusion behavior of aluminum alloy-Al2014 comparing with pure aluminum-Al1050, using different die angles (á=15, 30 and 75°) and different billet lengths (20, 28, 40 and 52mm). Results showed that the extrusion load increase when billet length increases for aluminum alloy (Al-2014) and pure aluminum (Al-1050). The results also showed that small die angles required higher extrusion load than large die angles. The Brinell hardness values showed that aluminum alloy (Al-2014) undergoes higher work hardening due to the presence of copper compared with the pure aluminum (Al-1050), in addition to formation of dead metal zone which resists the metal flow through the die opening. | ||
