Spray formed and rolled aluminium‐magnesium‐scandium alloys with high scandium content

Abstract: Aluminium-magnesium-scandium alloys offer good weldability, high corrosion resistance, high thermal stability and the potential for high strength by precipitation hardening. A problem of aluminium-scandium alloys is the low solubility of about 0.3 mass-% scandium when using conventional casting methods. The solution of scandium can be raised by higher cooling rates during solidification. This was realised by spray forming of Al-4.5Mg-0.7Sc alloys as flat deposits. Further cooling rates after solidification sho… Show more

“…In order to obtain a supersaturated solid solution however, high cooling rates would be required during casting to ensure rapid solidification of the slab and prevent formation of Al 3 (Sc, Zr) precipitates during casting. Studies on Al-Mg-Sc alloys cast through nonconventional methods such as Spray Forming[42] and Power Metallurgy[32]…”
