However, the formability and the surface quality of the final product of these alloys are not good if processing is performed at room temperature. Numerous studies have been conducted on these alloys to make their use possible as automotive body materials. Recent results show that the formability of these alloys is increased at temperature range from 200 to 300 ◦C and better surface quality of the final product has been achieved. The purpose of this paper is to review and discuss recent developments on warm forming of Al–Mg alloys. © 2008 Elsevier B.V. All rights reserved. Contents 1.
