Review of warm forming of aluminum-magnesium alloys
TL;DR: In this paper, the formability and surface quality of the final product of these alloys are not good if processing is performed at room temperature, however, they have been shown to increase at temperature range from 200 to 300°C and better surface quality has been achieved.

Forming of aluminum alloys at elevated temperatures – Part 1: Material characterization
TL;DR: A temperature-dependent anisotropic material model for use in a coupled thermo-mechanical finite element analysis of the forming of aluminum sheets was developed in this article, where the anisotropy properties of the aluminum alloy sheet AA3003-H111 were characterized for a range of temperatures 25 −260 −C (77 −500 −F) and for different strain rates.

The influence of strain-path changes on forming limit diagrams of A1 6111 T4
TL;DR: In this paper, the effects of changing strainpaths on forming limits of aluminum alloy 6111 T4 have been investigated by determining forming limit diagrams (FLDs) of specimens prestrained to several levels in uniaxial, plane strain and biaaxial tension, parallel and perpendicular to the prior rolling direction.

A review of recent advances in the application of blank-holder force towards improving the forming limits of sheet metal parts
E.J Obermeyer,S.A. Majlessi +1 more
TL;DR: A review of current industrial research and development in blank-holding technology, and its effect on the formability of sheet metals is presented in this article, where it is shown how the blank-holder force and the way it is applied on the blank affects the state of stress and strain within the part, and also influences the strain path.
