摘　　要：用真空感应电炉配制了镁 镧镨铈混合稀土(LPC)合金,用扫描电镜、透射电镜以及X射线面扫描等手段分析了该合金的微观组织。结果表明,添加的镧镨铈混合稀土只有少量固溶在镁基体中,绝大部分形成了稀土化合物,沿晶界呈网状分布。A kind of new Mg alloy containing rare-earth metal mixture (LPC) is prepared in a vacuum furnace.The microstructure of the alloy is observed under SEM and TEM,and the phase composition on the boundary is examined with EDS.The results indicate that most of the rare-earth element are concentrated along the boundary in network of metallic compound with a few solutioned into the Mg matrix.
