ALUMINUM-BASED ALLOY Russian patent published in 2020 - IPC C22C21/06 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy of aluminum-based materials and can be used in production of articles operating in corrosive media under action of high loads, including at high and cryogenic temperatures. Aluminum alloy with a structure consisting of aluminum solution and secondary emissions, contains, wt%: magnesium 4.0-5.5, manganese 0.3-1.0, iron 0.08-0.25, chrome 0.08-0.18, zirconium 0.06-0.16, titanium 0.02-0.15, vanadium 0.01-0.06, scandium 0.01-0.28, silicon 0.08-0.18, aluminum and unavoidable impurities - the rest, wherein at least 75% of each of the elements from the group of zirconium and scandium form secondary release with a lattice of type L1₂ in amount of not less than 0.18 vol% and particle size of not more than 20 nm.

EFFECT: invention is aimed at obtaining aluminum alloy with high manufacturability during deformation treatment with simultaneous improvement of mechanical properties.
