FIELD: special-destination alloys. SUBSTANCE: alloy of invention includes, as important ingredient, three- component phase so that alloy contains, wt %: magnesium at least 3-5, zirconium 0.05-0.15, manganese 0.05-0.12, titanium 0.01-0.2, and 0.05-0.5% of at least one element selected from scandium, terbium, cerium, and other lanthanides, including at least scandium, and further aluminum and indispensable silicon inclusions in amounts up to 0.1%. Invention also provides a part from above-defined alloy, which is appropriate for aircrafts, in particular for aircraft fuselage, for sea transport means or motor vehicles and which is made using welding, rolling, extrusion, or forging techniques. EFFECT: enabled manufacture of alloy characterized by high strength and high recrystallization threshold. 5 cl |
