Embodiment Construction
[0014] The specific technical solution of the present invention will be described in detail below through specific examples.
[0015] The invention is a high-strength and high-temperature resistant magnesium alloy, which mainly includes magnesium, aluminum, zinc, manganese, erbium, yttrium, zirconium and other elements, and its composition is as follows: aluminum 1-2%, zinc 2-3%, manganese 0.5% -1%, erbium 2-3.5%, yttrium 1.5-2%, zirconium 0.02-0.05%, silicon <0.02%, copper <0.002%, iron <0.002%, other impurities <0.005%, and magnesium as the balance.
[0016] Two specific implementations such as figure 1 as shown, figure 2 Shown are the corresponding room temperature mechanical properties of the two schemes as, image 3 Shown are the corresponding high temperature mechanical properties of the two schemes.
