Definitions
- New weldable, corrosion-resistant, high-magnesium aluminum-aluminum alloy especially for automotive applications
- 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.
- By adding rare earth elements or elements similar to rare earths, 0 in the aluminum-magnesium alloy dispersoids are generated, which according to the above. 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 is particularly suitable for body panels and has an addition of titanium and cerium over the known alloy.
- An alloy in which the ratio of manganese to scandium is less than two exhibits particularly favorable corrosion behavior.
- the titanium content in contrast to the known alloy, contributes to the increase in strength, in addition to its effect as a grain refining agent, since titanium can replace the zirconium in the ternary Al-Sc-Zr phase, although the solubility of titanium is lower than that of zirconium.
- the cerium additive also contributes to increasing the strength and further increasing the yield strength and thermal stability.
- a particularly strong and corrosion-resistant alloy 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 total mixture when a lanthanide mixture is used.
- the alloy tolerates silicon impurities up to 0.2% by weight; above all, the dynamic properties deteriorate.
