Abstract: A method of forming an aluminum alloy component including melting and solidifying an aluminum alloy, solution treating the aluminum alloy, and heat treating the aluminum alloy. The aluminum alloy includes scandium, zirconium, erbium, silicon, at least one of molybdenum and tungsten, manganese and the balance aluminum and incidental impurities. The concentration of the alloying elements, in atom %, is greater than 0.0 and less than or equal to 0.15 scandium, greater than 0.0 and less than or equal to 0.35 zirconium, greater than 0.0 and less than or equal to 0.15 erbium, greater than 0.0 and less than or equal to 0.2 silicon, greater than 0.0 and less or equal to 0.75 molybdenum when included, greater than 0.0 and less than or equal to 0.35 tungsten when included.

Abstract: This invention discloses a series of low-cost, castable, weldable, brazeable and heat-treatable aluminum alloys based on modifications of aluminum-manganese-based alloys, which turn all the non-heat treatable Mn-containing aluminum alloys into heat treatable alloys with high-strength, ductility, thermal stability, and resistance to creep, coarsening and recrystallization. These alloys inherit the excellent corrosion resistance of the Al—Mn-based alloys and can be utilized in high temperature, high stress and a variety of other applications. The modifications are made through microalloying with one or any combinations of tin, indium, antimony and bismuth at an impurity level of less than 0.02 at. %, which creates nanoscale α-Al(Mn,TM)Si precipitates with a cubic structure (wherein TM is one or more of transition metals, and Mn is the main element) in an Al(f.c.c.)-matrix with a mean radius of about 25 nm and a relatively high volume fraction of about 2%.
