An A-pillar on a motor vehicle is provided with a windshield flange for the securing of a windshield. The A-pillar is of single-part design in the region of the windshield and a wall region forming the windshield flange bounds a hollow cross section of the A-pillar. The windshield can be integrated indirectly in the A-pillar, which leads to a reduction in viewing angle obscuration.

The invention concerns a steel for lightweight construction, consisting of a multiphase structure. In the case of a duplex steel, it consists of mixed ferrite (α) and austenite (γ) crystals. In the case of a triplex steel, it comprises, additioally to said two phases, martensitic (ε) and/or (κ) phases. The volumetric weight of the inventive steel is low as a result of the high proportion of light alloys A1, Si Mn, Mg, Ga and Be. The inventive alloys have a volumetric weight of less than 7b/cm3.

摘要:
A motor vehicle having a stainless supporting frame structure or a stainless body-in-white, including a supporting frame structure and flat body components mounted thereon, the supporting frame structure being formed of rust-resistant steels as well as light metal alloys and/or plastics and the flat body components being formed of rust-resistant steels, light metal alloys and/or plastics, the surface of the supporting frame structure or the body-in-white being free of anti-corrosion coating or anti-corrosion painting. In addition, a method for manufacturing a motor vehicle having a corrosion-resistant body-in-white includes the steps of: manufacturing a supporting frame structure by joining and/or welding together rust-resistant steels; and mounting flat body components and/or body panels made of light metals, plastics, or rust-resistant steels, thereby forming the body-in-white. A color-providing surface coating of the body-in-white is directly applied to the uncoated surface of the rust-resistant steels, light metals, or plastics.

摘要:
The invention relates to a multi-layer composite plates and to a method for producing multi-layer composite plates. Said multi-layer composite plates are comprised of two outer metallic slabs which serve as top and base plates and which are joined to a deformable connecting material located therebetween. The top and base plates are joined to the connecting material by means of a foaming adhesive which fills the cavities remaining in the composite. The cavities remaining in the composite are completely or partially filled by the adhesive. According to the method for producing multi-layer composite plates, adhesive is introduced between the layers to be joined, and the adhesive is subjected to a thermal treatment. The adhesive is completely or partially hardened during the thermal treatment. In the case of the partially hardened adhesive, the adhesive is completely hardened during an additional thermal treatment only after the multi-layer composite plate is reshaped.
