The bending properties of AA2024-T3 aluminium alloy after localized laser assisted softening have been studied and
compared to untreated material. Single and multi-path laser scanning strategies are applied for achieving a predictable
and minimized springback. Process parameters for softening have been chosen based on FE modeling. In order to
investigate the softening, and to characterize the size of this softened region, hardness measurements were carried
out. Using a triple scanning path strategy springback was reduced by about 43% without changing the bending radius.
