结果表明，添加的镧镨铈混合稀土，只有少量固熔在镁基体中，绝大部分形成了稀土化合物，沿晶界呈网状分布。
The results indicated that a few of the rare-earth elements existed in the matrix, and most of that formed metallic composite with magnesium and distributed in the interface.
熔块完全融熔去除内部晶界之后，促进了取向性晶粒结晶。
Crystallization of the particles with preferred orientation was promoted, after the removal of internal interface through complete melting of the frit particles.
