  • Patent number: 11400507
    Abstract: A method for at least locally increasing the plasticity of a metal workpiece, which contains in particular an aluminum alloy, wherein the workpiece is irradiated in order to increase its temperature, and an associated production device, is provided. In order to be able to more quickly and thoroughly heat specific regions of a metal workpiece than other regions in a targeted manner, wherein it is possible to heat these regions more quickly and thoroughly with the same radiation output, while the surface of the workpiece remains largely unaffected, it is proposed that an absorbent be applied at least locally to the workpiece prior to irradiation thereof, wherein the degree of absorption of the absorbent for the radiation is greater than the degree of absorption of the workpiece for the radiation.
