The Warm Ductility of Commercial Aluminum Sheet Alloys 2005-01-1388

Warm forming offers the potential to produce complex aluminum components at high production volumes. The present paper evaluates the warm forming potential of seven different commercial aluminum alloys; 2008-T4, 5454-H32, 5754-O, 6111-T4, GZ45-T4, and two 5083 alloys. The mechanical behavior of these alloys is studied between 25°C and 300°C, and compared with a variety of materials from the literature, especially 5182, which has been well characterized. Analysis of total elongation, strain rate sensitivity, and strain localization demonstrate that 5083 and 5754 have promising warm forming performance.
