Abstract

The invention relates to the technical field of magnesium alloys, and particularly relates to a high-strength magnesium alloy. The high-strength magnesium alloy comprises the following feedstocks, inpercentages by weight, 0.1%-1% C, 2%-4% Ti, 4%-8% Si, 1.2%-2.2% Ca, 2.3%-3.8% Sn, 1%-2% Nd, 0.5%-1.0% Bi, 6%-10% Al, 0.5%-1.0% Zr, 1.0%-1.5% Mn, 4%-8% graphene, and the balance Mg and unavoidable impurities. According to the alloy, the flame retardance, the tensile strength and the yield strength of the magnesium alloy are improved by reasonably matching different elements and an intermediate alloy, and the alloy also has good room temperature and high-temperature mechanical properties, and the high-temperature creep resistance, the fatigue resistance and the heat storage resistance of the alloy are improved; in addition, the added graphene is a two-dimensional material with a single atomic layer thickness composed of SP2 hybrid carbon atoms, and the addition of the two-dimensional material can further improve the heat conduction performance and strength of the magnesium alloy.
