Abstract: The invention relates to an alloy, in particular a light metal alloy, having an alloy composition with at least three components and a eutectic structure that is obtained by cooling the alloy from a liquid state to a solid state, under the condition that a composition of the alloy lies in a field around a pseudoeutectic point (pE) of a phase diagram of the alloy, so that at least 85 mol % eutectic structure is present in the alloy. The alloy also relates to a method for producing an alloy of this type.

Abstract: The invention relates to a magnesium alloy. To obtain a magnesium alloy which exhibits both a high strength and also a high deformability, a magnesium alloy is provided according to the invention, comprising (in at %) 15.0% to 70.0% lithium, greater than 0.0% aluminum, and magnesium and production-related impurities as a remainder, wherein a ratio of aluminum to magnesium (in at %) is 1:6 to 4:6. The invention also relates to a method for producing the magnesium alloy.

Abstract: The invention relates to a method for increasing a corrosion resistance of a component formed with a magnesium-based alloy against galvanic corrosion, in particular micro-galvanic corrosion. According to the invention, an increase in a corrosion resistance against galvanic corrosion is achieved in a simple manner in that a surface layer of the component having a predefined thickness, which surface layer is formed with the magnesium-based alloy, is heated in order to configure the surface layer with a homogenized solid solution phase, whereupon the surface layer is cooled such that the surface layer is formed with a supersaturated solid solution phase. The invention furthermore relates to a corrosion-resistant component which is obtainable by a method of this type.

Abstract: A corona ignition device is described, with a central electrode, an insulator, in which the central electrode sits, a coil, which is connected to the central electrode, a metal housing, which holds the insulator and surrounds the coil, and a cover, which closes the metal housing at its end facing away from the insulator.

Abstract: An arrangement for fastening a bumper to a vehicle includes a deformation organ having one end for attachment to the bumper, and another end for sliding into a side member. The insertion section includes an inner wall which is stretchable when subjected to a tensile force. For elongating the inner wall, a material strip is received in a receiving space and equipped with a threaded breakthrough, which is aligned with a breakthrough of the adjacent transverse wall for receiving a tensile screw. The tensile screw extends through a breakthrough in a side member and exerts a force which elongates the inner wall. This initially provides a loose sliding-in of the insertion section in the side member and, following stretching of the inner wall, a tight seat of the insertion section in the side member.

Abstract: Disclosed is a profiled element (66) which is designed as a hollow profiled support section and is used for fastening a bumper to longitudinal beams (30) of a vehicle. Said profiled element (66) is assigned to a longitudinal beam (30) made of steel as an insertable section for the interior (32) of the longitudinal beam (30). The final edge (67) of at least two opposite walls (68) of the insertable section of the profiled element (66), which is made of a light metal material, is attached inside an insertion member (70) which, as a separation layer, prevents adjacent surfaces that are made of light metal and iron-carbon alloys from corroding. The insertable section is inserted into the longitudinal beam (30) along with the insertion members (70).

Abstract: A bumper with an attachment member to be made thereon for the purpose of mounting the bumper onto longitudinal beams of a vehicle, is such that section walls acting as compressive and tensile struts and a pair of flanking walls joining them form a hollow section. The attachment member is in the form of a hollow section exhibiting at least one side wall and two transverse walls following on therefrom with a length of hollow section with the longitudinal beam. The hollow section is in the form of a push-fit length matching the inner cross-section of the longitudinal beam. The other end region of the attachment member is provided with collar-type parts projecting from their end edges and aligned approximately parallel to the transverse walls. In a use position, the collar-type parts of the attachment member are aligned with the flanking walls of the bumper and are releasably attached to it. The bumper is bolted to the collar-type parts of the attachment member.
