Higher strength and superior corrosion resistance of Al-Mg alloys have made them the most widely used aluminum alloys for various forming applications in automotive and marine sectors. However, the increasing Mg content causes a deteriorating effect on the formability of Al-Mg alloys. The Nakajima test was conducted on AA5052 and AA5083 alloy sheets at room temperature using ARAMIS-GOMTM; system for dynamic measurements of 3D displacements and 3D surface strain to understand the impact of varying Mg content on formability of Al-Mg alloys. The test result showed higher formability in AA5052 alloy with 2.55 wt. % Mg as compared to AA5083 with 4.42 wt. % Mg. The distribution of constituent particles/ intermetallics were also quantified using optical microscopy for both the alloy samples. Finite element analyses of FLC (Forming Limit Curve) prediction were also performed where various necking criteria were implemented and compared with the experimental results.
