Estimating the term…
A method for producing a semifinished product with locally different material thicknesses may involve preparing a multilayer, metal material composite, which has a plurality of layers with different ductilities, and rolling the material composite in a method for flexible rolling through a rolling gap formed between two rollers. The rolling gap may be configured such that regions with different material thicknesses are formed. In some cases, the multilayer, metal material composite is rolled at room temperature. Further, the plurality of layers of the multilayer, metal material composite may include a first outer layer disposed on a first side of a middle layer and a second outer layer disposed on a second side of the middle layer, with the second side of the middle layer being opposite the first side.
A method for producing a semifinished product with locally different material thicknesses, the method comprising:
A method for producing a structural component with locally different material thicknesses, the method comprising:
A semifinished product with locally different material thicknesses, the semifinished product comprising a plurality of layers with different ductilities, wherein the plurality of layers comprises a first outer layer disposed on a first side of a middle layer and a second outer layer disposed on a second side of the middle layer, the second side of the middle layer being opposite the first side, wherein the plurality of layers has a symmetrical layer structure with respect to the middle layer, wherein the first and second outer layers have a higher ductility than the middle layer.
