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.
Aluminum sheet alloys only typically posses moderate formability at room temperature limiting their design applications.
This process is called warm forming.

Results indicate that the formability of this material at cold and warm temperatures is better than at.
The warm press forming of aluminium alloy sheets promoted a great interest and has been studied for several decades.
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.

In this study uniaxial tensile deformation behaviour of 5754 aluminium magnesium alloy sheet was extensively studied at cold 60 to 0 c and warm room to 250 c forming temperatures and a strain rate range of 0 0016 0 042 s 1.
Warm forming of these alloys can significantly improve their formability and this is the main.
