摘要
A high temperature creep-resistant aluminum alloy microalloyed with manganese and molybdenum and/or tungsten is provided. 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, and greater than 0.0 and less than or equal to 1.5 manganese. And the total concentration of Zr+Er+Sc is greater than or equal to 0.1.
