Abstract
The invention discloses a high-strength and high-temperature-resistant magnesium alloy, and belongs to the field of metallic materials. The magnesium alloy mainly comprises elements of magnesium, aluminum, zinc, manganese, erbium, yttrium, zirconium and the like, the magnesium alloy is composed, by weight percentage, of 1-2% of the aluminum, 2-3% of the zinc, 0.5-1% of the manganese, 2-3.5% of the erbium, 1.5-2% of the yttrium, 0.02-0.05% of the zirconium, less than 0.02% of silicon, less than 0.002% of copper, less than 0.002% of iron, less than 0.005% of other impurities and the balance magnesium. According to high-strength and high-temperature-resistant magnesium alloy, the elements such as the magnesium, the aluminum, the zinc, the manganese, the erbium, the yttrium and the zirconium are added into the magnesium alloy, room-temperature strength and corrosion resistance of materials are improved, tensile strength, elongation and high-temperature strength of the magnesium alloy are greatly improved, and the magnesium alloy can work under the temperature ranging from 200 DEG C to 300 EDG C for a long time.
