Introduction sheet metal aluminum alloys are prime candidates for use in the automotive industry because of their good strength and stiffness to weight ratios. Results indicate that the formability of this material at cold and warm temperatures is better than at. Now let us have a look at the considered drawing process. A paper by takuda et al.

Contains the first references relating to this subject see also 2 4. Aluminum sheet alloys only typically posses moderate formability at room temperature limiting their design applications. Warm and hotforming processes are characterized by an equilibrium of formability of the sheet material at certain temperatures and the strength needed to transmit the drawing forces in the sheet. Mj painter and r pearce 1980 the elevated temperature behaviour of some aluminium magnesium alloys a paper presented at the 11th iddrg biennial congress metz france june 1980 google scholar.

An exemplary aluminum alloy. In the 1970 s an interest in warm forming emerged and it was discovered that an aluminium 6 magnesium alloy could give a total elongation of about 300 at about 250 c at the appropriate strain rate. Warm forming of these alloys can significantly improve their formability and this is the main. What defines the drawability under different thermal conditions.

Status and research opportunities new developments in sheet metal forming international conference. Drawing tests are performed on. This process is called warm forming. Carsley et al aluminum forming technologies.

The research in this domain was accelerated since 1980s 5 12.
