More Information
Summary:The invention discloses a high-temperature-resistant rare earth magnesium alloy which consists of the following components in percentage by mass: 3-5 percent of Y, 0.5-2.5 percent of Nd, 0.5-2.5 percent of Sm, 0.2-1 percent of Sb, impurity elements Si, Fe, Cu and Ni of which the total amount is less than 0.2 percent, and the balance of Mg. The high-temperature-resistant rare earth magnesium alloy is stable in high-temperature performance and has high high-temperature tensile strength, and the tensile strength can reach over 200Mpa at the temperature of 300 DEG C; and compared with the commercial heat-resistant magnesium alloy WE43 alloy, the high-temperature-resistant rare earth magnesium alloy has high strength performance and high application temperature and has wide application prospect in aspects such as aerospace, automobile industry and military hardware.
