摘 要: 通過高分辨透射電鏡和帶能譜透射電鏡觀察,經(jīng)選區(qū)電子衍射和微區(qū)化學成分分析,發(fā)現(xiàn)ZnAl27復合材料中,SiC顆粒周邊存在著大量的CuZn4化合物。CuZn4依附于SiC顆粒形核,其沿SiC晶面長大速率大于垂直方向的長大速率。

Abstract:It was found that CuZn4 can nucleate on the surface of SiC particle and grow up at higher speed along SiC than the vertical direction through selected area electron diffraction and EDS analysis by means of HREM and AEM.
Key words: zinc-based allay; SiC particle; CuZn4 compound
