Abstract (en)
[origin: WO2017182629A1] The invention relates to a method for at least locally increasing the plastic deformability of a metal workpiece (5), which has an aluminum alloy in particular. The workpiece (5) is supplied with a radiation in order to increase the temperature of the workpiece. The invention also relates to a corresponding manufacturing device. The aim of the invention is to allow a higher and faster heating of specific regions of a metal workpiece in a controlled manner compared to other regions, wherein a higher and faster heating is to be achieved using the same radiation power while the surface of the workpiece is to be influenced as little as possible. This is achieved in that an absorption agent (10) is applied at least locally onto the workpiece (5) prior to supplying the workpiece (5) with the radiation. The degree of absorption of the absorption agent (10) for the radiation is higher than the degree of absorption of the workpiece (5) for the radiation.
