摘　　要：研究了Cd对Mg-Cd二元合金组织和性能的影响。通过XRD、SEM和EDS对加入Cd镁合金金相进行了检测。研究结果表明:在纯镁中加入微量的Cd能明显的细化组织,并且加入从0%到0.7%(质量分数)的Cd后,在Mg-Cd合金中没有新相产生,Cd均匀、弥散的固溶在镁基体中,使合金的冲击韧度、布氏硬度分别提高了52.9%,11.9%,且随着Cd加入量的增加,Mg-Cd二元合金的力学性能在逐渐的增加。The effects of Cd on the microstructure and the mechanical properties of Mg-Cd magnesium alloy were investigated. The Mg-Cd binary magnesium alloy was analyzed by metallograph, XRD, SEM and EDS examinations. The results show that the microstructure of the Mg-Cd magnesium alloy is refined obviously by adding a little amount of Cd. When Cd addition（wt%） is from 0% to 0.7%, the alloy is composed of α-Mg matrix. Cd dissolves in the matrix to form a solid solution, and there is no new phase formed, which contributes to the increase of the impact toughness, Brinell hardness of the experimental alloy by 52.9%, 11.9%, respectively. With the Cd content increasing, the mechanical properties of Mg-Cd magnesium alloy are improved accordingly.
