| Abstract Scope |
Aluminium (Al) alloys play a critical role for the transportation applications where weight reduction is a key aspect; however, the poor formability at room temperature limits their application for complex components. An innovative methodology to overcome this limitation is based on subjecting the material to a local, short-term heat treatment before the stamping to obtain a tailored distribution of properties. In addition, Continuous Bending under Tension uses the action of three rollers to remarkably increase the total elongation to failure. In the present work, the combination of the two approaches is investigated to improve the formability at room temperature of a strain hardenable 5xxx Al alloy, AA5754-H32. Specimens were subjected to both CBT and pre-forming heat treatments. Specimens were then subjected to hardness measurements and tensile tests at room temperature in order to assess the plastic behaviour and evaluate the effect on the material formability. |
