The feasibility of forming a third generation aluminium-lithium alloy (AA2060) into a complex shaped panel component, was studied by using an advanced forming technology called solution heat treatment, cold die forming and in-die quenching (HFQ*) process. The flow stresses of AA2060 were obtained at different temperatures ranging from 350 to 520 oC at the strain rate of 1 s−1. The suitable temperature to achieve the adequate ductility was found at 470 oC. By forming the AA2060 blanks at the optimum forming temperature, experimental results exhibited the feasibility for forming complex-shaped AA2060 components. The formed components were analysed through strain measurements. The post-form mechanical properties of AA2060 were assessed using hardness and tensile tests. * HFQ® is a registered trademark of Impression Technologies Ltd.
