摘　　要：研究了复合添加Er和Sr对ZM5镁合金微观组织,力学性能,耐腐蚀性能的影响。结果表明,复合添加Er、Sr可有效细化合金第二相。ZM5-0.6%Er-0.15%Sr合金抗拉强度和伸长率分别达到普通ZM5镁合金的91.3%和107.5%,腐蚀速率为普通ZM5镁合金的50%。The effects of tiny Er and Sr on the microstructure, mechanical properties and corrosion resistance of the magnesium alloy ZM5 were investigated. The results show that the secondary phase of the alloy is refined when Er and Sr is added into the alloy simultaneously. The tensile strength and elongation of the alloy ZM5-0.6%Er-0.15%Sr is 91.3% and107.5% of those of common alloy ZM5 respectively, and the corrosion rate reach 50% of the magnesium alloy ZM5.
