Embodiment Construction
[0020] The technical solutions of the present invention will be further limited below in conjunction with specific embodiments, but the scope of protection is not limited to the description.
[0021] For high-strength and heat-resistant magnesium alloys, the raw material components are magnesium-rare earth master alloys, which are 9.3-10.5% in terms of rare earths; magnesium-zirconium master alloys, which are 0.5% in terms of zirconium, and the rest are magnesium ingots.
[0022] In certain embodiments, the magnesium-rare earth master alloy is optimal at 10.5% rare earth.
[0023] In certain embodiments, the magnesium-rare earth master alloy is one of Mg-Gd, Mg-Y, Mg-Nd, Mg-Ce, Mg-La, Mg-Pr, Mg-Gd.
[0024] In certain embodiments, the magnesium-rare earth master alloy is a mixture of at least two of Mg-Gd, Mg-Y, Mg-Nd, Mg-Ce, Mg-La, Mg-Pr, Mg-Gd in any ratio.
[0025] In some embodiments, the specific composition of the magnesium-rare earth master alloy is Mg-Gd:Mg-Y:Mg-Nd=5....
