  • Publication number: 20220267881
    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.

  • Publication number: 20220259705
    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.

  • Publication number: 20220081778
    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.
