Warm forming of aluminium magnesium alloy sheet.

A paper by takuda et al. 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. Working technology 2 p 279 crossref google scholar 2. This was a non heat treatable strain hardening alloy but inevitably was of reduced cold ductility because of the alloying addition.

An exemplary aluminum alloy. Now let us have a look at the considered drawing process. Pearce department of materials cranfield institute of technology cranfield england received june 21 1978 industrial summary at this time when energy conservation. A study is carried out on the feasibility of using warm forming at temperatures from 100 to 250 c in order to improve the makeability of aluminium sheet components.
