The invention relates to a heat-resistant creep-resistant magnesium alloy and a preparing method thereof, which belong to the field of metal materials and metallurgy. The heat-resistant creep-resistant magnesium alloy is mainly formed by the following components in percent by mass: 7-8% of Sm, 0.7-0.9% of Nd, 1.5-2.0% of Zn, 1.0-1.3% of Ca, 1.2-1.5% of Mn, 1.1-1.3% of Al and the balance of Mg and inevitable impurities. The magnesium alloy in the invention has good tensile strength and better creep resistance under a high temperature, and has better application prospect. 本发明涉及种耐热抗蠕变镁合金及其制备方法，属于金属材料及冶金领域。本发明中的耐热抗蠕变镁合金，主要由以下质量百分比的组分组成：7～8％Sm，0.7～0.9％Nd，1.5～2.0％Zn，1.0～1.3％Ca，1.2～1.5％Mn，1.1～1.3％Al，余量为Mg和不可避免的杂质。本发明中的镁合金在高温下具有很好的抗拉强度和良好的抗蠕变性能，具有良好的应用前景。
