Abstract
Superplastic behavior of certain metals and alloys having very fine grains, very large tensile elongations are obtained within certain temperature ranges at low strain rates. These alloys can be formed into complex shapes by superplastic forming, a process that employs common metalworking techniques. This paper aims to study the formability characteristic for aluminium material (Al 7075) by considering variable parameters such as sheet thickness of 1.75 and 1.5 mm and the temperature of 520°C and 530°C.
