Изобретение относится к области металлругии, в частности к сплавам на основе магния, предназначенных для применения в качестве конструкционных материалов в авиации, космонавтике, автомобилестроении и других отраслях современной техники. Предложен сплав на основе магния, содержащий литий, алюминий кадмий, цинк, марганец, редкоземельный металл, иттрий, цирконий, бериллий. Новым является то, что он дополнительно содержит иттрий, цирконий, бериллий в следующем соотношении, мас.%: литий 6,0 - 11,0, алюминий 1,0 - 6,0, кадмий 3,0 - 5,0, цинк 0,5 - 2,0, марганец 0,05 - 0,5, редкоземельный металл 0,05 - 0,15, иттрий 0,01 - 2,0, цирконий 0,001 - 0,1, бериллий 0,001 - 0,05, магний - остальное. Предлагаемый сплав дает возможность получать деформированные полуфабрикаты из магниевых сплавов, содержащих литий, с более высокими прочностными характеристиками как при комнатной (на 5 - 6%), так и при повышенной (20 - 25%) температурах, и с более, чем в 10 раз меньшей склонностью к ползучести по сравнению с существующими магниевыми сплавами, содержащими литий.The invention relates to the field of metallurgy, in particular to magnesium-based alloys intended for use as structural materials in aviation, astronautics, automotive and other branches of modern technology. A magnesium-based alloy containing lithium, cadmium aluminum, zinc, manganese, a rare-earth metal, yttrium, zirconium, and beryllium is proposed. New is that it additionally contains yttrium, zirconium, beryllium in the following ratio, wt.%: Lithium 6.0 - 11.0, aluminum 1.0 - 6.0, cadmium 3.0 - 5.0, zinc 0 5 - 2.0, manganese 0.05 - 0.5, rare earth metal 0.05 - 0.15, yttrium 0.01 - 2.0, zirconium 0.001 - 0.1, beryllium 0.001 - 0.05, magnesium - the rest. The proposed alloy makes it possible to obtain deformed semi-finished products from magnesium alloys containing lithium with higher strength characteristics both at room temperature (by 5 - 6%) and at elevated (20 - 25%) temperatures, and with more than 10 times less prone to creep compared to existing magnesium alloys containing lithium.
