Definitions

  • the invention relates to a weldable, corrosion-resistant, high-magnesium aluminum-magnesium alloy, which is an essential component of a ternary aluminum-scandium-zirconium phase contains.
  • a weldable, corrosion-resistant, high-magnesium aluminum-magnesium alloy which is an essential component of a ternary aluminum-scandium-zirconium phase contains.
  • Such an alloy is for example from the US 5,624,632 and is known for its low density, high strength and Corrosion resistance is of particular interest for aerospace applications.
  • US Patent generate higher strength and corrosion resistance. In terms of weldability such an alloy can the above. No indication can be found in U.S. patent
  • this new alloy is particularly suitable for Body panels suitable and has an addition of the known alloy Titanium as well as cerium.
  • An alloy shows a particularly favorable corrosion behavior the ratio of manganese to scandium is less than two.
  • known alloy contains titanium, in addition to acting as a grain refining agent, to increase the strength since titanium replaces the zirconium in the ternary Al-Sc-Zr phase can, but the solubility of titanium is lower than that of zirconium.
  • the cerium additive carries also to increase strength and continue to increase the yield strength as well as thermal stability.
  • a particularly strong and corrosion-resistant alloy contains at least 0.15% by weight Scandium.
  • the addition of lanthanides is advantageously in a weight% range between 0.05 and 0.35, this range being different when using a lanthanide mixture relates to the total mixture.
  • the alloy tolerates silicon impurities up to 0.2% by weight; above all, the dynamic properties deteriorate.
