本文用透射电镜（ＴＥＭ）的衍射技术和高分辨电镜（ＨＲＴＥＭ）研究了用原位固－气－液三态反应法制备的原位ＴｉＣ－ＡｌＮ／Ａｌ复合材料中ＡｌＮ颗粒与Ａｌ界面的微观组织结构，发现ＡｌＮ／Ａｌ界面两侧晶体的两个晶面存在平行关系：（１０１）ＡｌＮ∥（１１１）Ａｌ。作者从金属固溶和金属结晶理论出发，分析了ＡｌＮ／Ａｌ界面微结构的形成机制，较好地解释了原位ＴｉＣ－ＡｌＮ／Ａｌ复合材料中界面结合较好的原因。
In this paper, the microstructures of AlN particles and Al interface in in-situ TiC-AlN / Al composites prepared by in-situ solid-gas-liquid three-state reaction were investigated by transmission electron microscopy (TEM) diffraction and high resolution electron microscopy (HRTEM) The results show that the two crystal planes of AlN / Al interface have parallel relationship: (101) AlN∥ (111) Al. Based on the theory of metal solution and metal crystallization, the author analyzed the formation mechanism of AlN / Al interface microstructure and better explained the reason of good interface bonding in in situ TiC-AlN / Al composite.
