Abstract: This disclosure relates to the field of metallurgy, namely, to the composition of an aluminum-based heat-resistant alloy and a powder from it to be used for the production of parts using additive technologies. A new aluminum-based material has been created, which is intended for producing a powder and its utilisation in the additive production of various products, which has high processability at laser melting and high strength characteristics in the heat-treated state: the yield strength exceeding 400 MPa, the ultimate strength exceeding 470 MPa, and elongation at break of at least 4%. The powdered aluminum material contains copper, magnesium, manganese, cerium, silicon, zirconium and/or titanium, where the material contains thermally stable Al8Cu4Ce dispersoids with a size of less than 1 ?m, which are formed at crystallisation rates of at least 103 K/s, which contribute to the material strengthening under operating conditions at room and elevated temperatures.

Abstract: The invention relates to the field of metallurgy, namely to new heat-resistant aluminum alloys used in additive technologies. The alloy includes nickel, manganese, iron, zirconium, cerium, at least one element selected from the group: copper, magnesium, zinc, and at least one element selected from the group: silicon, calcium, where Ni>Mn+Fe, one or more eutectic phases of the type of Al3Ni, Al16Mn3Ni, Al9FeNi, which are thermally stable, and dispersoids of the Al3Zr type, which ensure an ultimate strength of a resulting product of at least 370 MPa. The technical effect is the development of an aluminum material used in the form of a powder, which has good processability when printing and increased strength characteristics at room temperature after printing, without a significant decrease in strength after annealing.

Abstract: The present disclosure relates to metallurgy, more particularly to a composition and a process for producing part blanks and finished parts from aluminum-based alloys including but not limited to using selective laser melting processes. The proposed aluminum-based alloy comprising magnesium, zirconium and scandium for atomization an aluminum powder therefrom and subsequent producing finished parts by additive technologies has a reduced content of scandium and further comprises oxygen and calcium with a limited size of the oxide film and a moister content.

Abstract: The proposed invention relates to the field of metallurgy, namely, to aluminium-based alloys used for the production of powders applied in the manufacture of parts using additive technologies, including the method of selective laser melting. A powder aluminium material containing magnesium, chromium and zirconium is proposed, which additionally contains boron and at least one element from the group of manganese, iron and nickel, with a given ratio of components. The technical result is an increase in the strength of aluminium alloy for the manufacture of parts using powder and additive technologies while maintaining a high level of elongation, high thermal stability and the absence of defects such as hot cracks.
