摘要： A method for producing a composite material, particularly a steel composite material, may involve providing a first workpiece and a second workpiece, producing a bonded connection between said first and said second workpiece in order to form a provisional composite, and rolling said provisional composite in order to form the composite material. During the rolling, the bonded connection may be at least partially released, in the form of a predetermined breaking point. The rolling may be performed as hot rolling. Further, the method may involve substantially hermetically sealing the provisional composite by way of a sealant. The first and second work pieces, moreover, may be peripherally connected by way of the bonded connection along an edge area of a contact surface formed by the first and second work pieces.

摘要： A process may be used to produce a composite material in a rolling plant. The process may involve providing a first workpiece and a second workpiece, which workpieces are configured in the form of a temporary composite. The process may further involve producing a planar connection between the first and second workpieces in the temporary composite by prerolling. Still further, the process may involve rolling, in particular hot rolling, the temporary composite to form the composite material after the planar connection has been produced by prerolling. The process may also involve heating the temporary composite before and/or after the prerolling.

摘要： The present invention relates to a steel material composite, comprising a core layer of a higher-strength or high-strength steel and, integrally bonded to the core layer on one or both sides, an outer layer of ferritic, chemically resistant steel. Corresponding flat steel products are distinguished by favourable properties with respect to their strength, ductility, low sensitivity to hydrogen-induced crack formation and favourable corrosion resistance. The present invention also relates to a method for producing a corresponding steel material composite and to the use of such steel material composites in vehicle structures and in particular in bodywork structures.

摘要： A steel workpiece may have an edge region and a core region. The object of specifying a steel workpiece wherein a maximum near-surface strength and nevertheless favorable surface properties are achieved, especially favorable scaling characteristics during hot rolling, is achieved in that the steel workpiece may be softer in the edge region than in the core region, and in that a sum total of alloy constituents C, Si, Mn, Cr, and N of the steel workpiece overall is greater than 1.45% by weight. And in some examples the sum total of the alloy constituents C, Si, Mn, Cr, and N of the steel workpiece is less than 4.5% by weight.

摘要： 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.

摘要： Methods for producing a flat product from an iron-based shape memory alloy may involve casting a melt comprised of iron, alloying elements, and impurities into a strip having a thickness of 1-30 mm and cooling the melt as the strip is formed. A twin-roll caster may be employed to help cool and form the melt into the strip. The resultant flat product is highly resistant to bending and is robust under pressure and torsion.
