FIELD: metallurgy; production of magnesium alloys which are creep-resistant at high temperatures.
SUBSTANCE: magnesium-based alloys are used for manufacture of articles and castings, cylinder blocks for example. Proposed alloy contains neodymium, cerium and/or lanthanum, zinc, zirconium, manganese, oxidation inhibitor and magnesium. Alloy may additionally contain titanium, hafnium, aluminum, copper, nickel, silicon, silver, yttrium, thorium, iron and strontium. Alloys and articles manufactured from them possess high mechanical properties and high creep resistance at high temperature.
EFFECT: enhanced creep resistance of alloys.
