Definitions

  • the invention relates to a weldable, corrosion-resistant, high-magnesium aluminum-magnesium alloy, which contains a ternary aluminum-scandium-zirconium phase as an essential component.
  • a weldable, corrosion-resistant, high-magnesium aluminum-magnesium alloy which contains a ternary aluminum-scandium-zirconium phase as an essential component.
  • Such an alloy is known, for example, from US Pat. No. 5,624,632 and, due to its low density, high strength and corrosion resistance, is of interest above all for applications in aviation.
  • dispersoids are produced in the aluminum-magnesium alloy, which according to the above-mentioned.
  • US patent produce higher strength and corrosion resistance.
  • the weldability of such an alloy the above-mentioned. No information can be found in US patent.
  • This object is achieved by an aluminum-magnesium alloy according to claim 1.
  • this new alloy has above all a significantly lower manganese content, surprisingly showing improved corrosion resistance, especially in the sensitized state of the parts made from this alloy, for example when cold-formed parts are exposed to an elevated temperature for a long time. be set. It is believed that these positive properties are mainly determined by the ratio of manganese to scandium. This shows an improved corrosion resistance with a ratio Mn: Sc ⁇ 2.
  • the titanium content in contrast to the known alloy, also contributes to the increase in strength, in addition to the effect as a refining agent, since titanium is the zirconium in the ternary Al-Sc-Zr phase can replace, but the solubility of titanium is lower than that of zirconium.
  • scandium can be replaced by terbium or cerium at least within certain limits. When replacing with terbium, however, a greater addition than that of the replaced scandium is required to achieve the same properties.
  • a particularly favorable alloy for aircraft applications contains at least 0.15% by weight of scandium.
  • the addition of lanthanides advantageously ranges between 0.05 and 0.35% by weight, this range relating to the overall mixture when using a lanthanide mixture.
  • the alloy tolerates up to 0.1% by weight of silicon; above all, the dynamic properties deteriorate.
