Beschreibung
Zusammenfassung:	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 μm, 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.
