在扫描电镜上观察和研究了Al2 O3 ·SiO2 /Zn RE复合材料的凝固组织及其界面。结果表明

在复合材料中

Al2 O3 ·SiO2 纤维与基体间存在致密界面层

适当的化学反应可改善纤维与基体的结合 ;在凝固过程中

Al2 O3 ·SiO2 纤维可作为锌合金共晶体非自发形核的衬底

纤维 /基体界面上的硅在共晶体的共生生长过程中起了领先相作用

导致复合材料的共晶转变由铝硅共晶转变和锌铝共晶转变两者组成

Solidification microstructure of Al

·SiO

/Zn-RE composites and its interface were observed by SEM.The results showed that there exists a compact interface between Al

·SiO

fibre and matrix and that the proper chemical reaction can be helpful to improve the bonding of the fibre and matrix.Al

·SiO

fibre can be taken as a substrate of heterogeneous eutectic nucleation of the zinc alloy

and the silic phase in fibre/matrix interface is prior to growing in couple growth during solidification

which realizes the Al-Si eutectic transformation and Zn-Al eutectic transformation in the composites.
