Embodiment 1
[0016] The high-strength creep-resistant magnesium alloy of this embodiment is composed of the following components by mass percentage: 4.0% Y, 2.5% Sm, 0.3% Sb, the total mass percentage of impurity elements Si, Fe, Cu, Ni is less than 0.2%, and the rest The amount is Mg. The sum of the mass percentages of Y and Sm is 6.5%.
[0017] The high-strength creep-resistant magnesium alloy of this embodiment is formed by melting and casting magnesium, antimony and intermediate alloys Mg-Y and Mg-Sm as raw materials and undergoing solid solution and aging heat treatment, specifically:
[0018] The alloy is formulated according to the above ingredients, and the melting and casting process is as follows: using a corundum crucible and an intermediate frequency induction furnace, in CO 2 +SF 6 Melting under the protection of mixed gas, when the temperature of magnesium liquid rises to 750°C, it is cast into a steel mold to obtain Mg-4.0Y-2.5Sm-0.3Sb as-cast alloy, followed by heat treat...
