Abstract: The effect of localized laser hardening on the dimensional accuracy of incrementally
formed steel sheets has been studied. By dynamically heating by means of laser beam scanning
(500W Nd:YAG) the temperature of the sheet reaches the austenization temperature and by
subsequent self-quenching a hard martensitic structure is formed. Using FE modeling optimum
processing parameters for transformation hardening were selected. Hardness tests were performed
in order to investigate the hardness profile along the depth and width of the laser hardened zone.
Experimental results reveal that generation of a selectively hardened martensitic band,
