Abstract
Forming of aluminum sheets at warm forming temperatures has been investigated as an alternative manufacturing process for improving formability compared with forming at room temperature. However, the forming technology should be developed to increase the application field, especially in the predication of formability and the failure in order to design the process and die outcomes. The results obtained during this study showed that the formability of annealed Al-alloy (Al-2024-O) is increased by increasing temperature. Its formability is significantly improved compared with the precipitation hardened alloy (Al-2024-T3). The possibility of forming (Al-2024-T3) sheet metal at moderate temperatures, with acceptable formability and higher strength for structural parts is much better if compared to the annealed condition (Al-2024-O).
Key words : warm forming, formability, aluminum alloy (2024)
