Bending of sheet aluminum alloy assisted by arc pretreatment

Bending of sheet aluminum alloy assisted by arc pretreatment Considering the poor formability of aluminum alloys at room temperature, this study proposes a stamping technique assisted by arc pretreatment that locally modifies the material properties. V-shape bending tests are conducted on the arc-treated specimens. The formability (bendability in particular) of 6061-T6 aluminum alloy is significantly improved by arc pretreatment and the springback is reduced as well. The reasons for formability improvement and springback reduction are analyzed through the microstructure, mechanical property, and fracture morphology of the heat-affected zone. The hardness at different locations within the heat-affected zone before and after bending is also tested. Finally, the advantages of arc pretreatment over other traditional forming processes at elevated temperatures are explained. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png The International Journal of Advanced Manufacturing Technology Springer Journals
