  • Publication number: 20220325387
    Abstract: The invention relates to the field of metallurgy of aluminum-based materials and may be used for the manufacture of products operating in corrosive environments under high loads, in particular, at elevated and cryogenic temperatures. The new aluminum alloy with a structure comprising an aluminum solution, precipitations and an eutectic phase formed by elements such as magnesium, manganese, iron, chromium, zirconium, titanium and vanadium, is claimed. Besides, the alloy additionally contains silicon and scandium, wherein at least 75% of the share of each element from the group of zirconium and scandium form precipitations with the lattice of type L12 in the amount of at least 0.18% vol and the particle size of no more than 20 nm, with the specified redistribution of alloying elements.

  • Patent number: 11168383
    Abstract: The invention relates to the field of metallurgy of aluminum-based materials and can be used to produce articles (including welded structures) operated in corrosive environments (humid atmosphere, fresh or sea water, and other corrosive environments) and under high-load conditions, including at elevated and cryogenic temperatures. A new, inexpensive, high-strength aluminum alloy is provided with high physical and mechanical properties, performance, and corrosion resistance, in particular, high mechanical properties after annealing (tensile strength of at least 400 MPa, yield point of at least 300 MPa, and relative elongation of at least 15%) and high performance in deformation processing; wherein high performance in deformation processing is provided due to the presence of eutectic Fe-containing alloy phases, accompanied by increased mechanical properties due to the formation of compact particles of eutectic phases and secondary separation of the Zr-containing phase with the L12 crystal lattice.
