A Mg—Li—Al—Zn alloy is disclosed. The Mg—Li—Al—Zn alloy comprises, in weight percent: 5-15% Li, 1.5-9.0% Al, 0.5-1.5% Zn, 0.4-1.3% Y, 0.18-1.01% Nd, 0.09-0.65% Ce, and the balance Mg and incidental impurities. Experimental data have proved that, this novel Mg—Li—Al—Zn alloy has a flashover temperature in a range between 620° C. and 700° C., such that the flashover temperature of the specifically-designed Mg—Li—Al—Zn alloy is greater than that of commercial LAZ521, LAZ721, LAZ771, LAZ921, and LAZ1491 alloys. Therefore, the Mg—Li—Al—Zn alloy of the present invention can be processed to be a structural article through air melt and casting process.

The present disclosure discloses a Mg—Gd—Y—Zn—Zr alloy with high strength and toughness, corrosion resistance and anti-flammability and a process for preparation thereof. Components and mass percentages in the Mg—Gd—Y—Zn—Zr alloy are: 3.0%≤Gd≤9.0%, 1.0%≤Y≤6.0%, 0.5%≤Zn≤3.0%, 0.2%≤Zr≤1.5%, the balance being Mg and inevitable impurities. The process for preparation thereof comprises: adding pure Mg into a smelting furnace for heating, then introducing mixed gases of CO.sub.2 and SF.sub.6 into the furnace for protection; adding other raw materials in sequence when the pure Mg is completely melted; preparing an ingot; conducting a homogenization treatment on the ingot prior to extrusion; conducting an aging treatment on the extruded alloy. The present invention obtains a wrought magnesium alloy having both superior overall performances and good fracture toughness, corrosion resistance and anti-flammability, with a small amount of rare earth element by adjusting the proportion of the alloy elements and by conventional casting, extrusion and heat treatment processes.
