The aluminium alloy is rapidly-solidified and plastically consolidated and comprises between 3.00 and 10.00 wt.% of magnesium and between 1.00 and 6.00 wt.% of manganese. It moreover comprises dispersoid forming transition elements which are selected from the group consisting of chromium, vanadium, titanium, zirconi...

The lightweight aluminium or magnesium alloy comprises aluminium or magnesium and one or more alloying elements, including dispersoid forming elements increasing the liquidus temperature of the alloy. The alloy is ejected in a molten state from at least one nozzle (5) and is rapidly solidified. The lightweight alloy...
