Experimental Investigation on the Formability of 7075 Al – Alloy Sheet in Superplastic Forming Technique

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.
