利用分析透射电镜研究了液态搅拌铸造原始态与氧化态ＳｉＣＰ以及ＳｉＯ２（Ｐ）增强Ａｌ－４ｗｔ％Ｍｇ基复合材料的界面反应情况。结果在原始态和氧化态碳化硅颗粒表面观察到细小的ＭｇＯ，石英粒子在高温下与基体中的镁反应生成ＭｇＡｌ２Ｏ４，并运用扩散理论分别解释了其反应机制。
Transmission electron microscopy (TEM) was used to investigate the interfacial reaction between SiSC and SiO2-P-reinforced Al-4wt% Mg matrix composites prepared by liquid state mixing. Results Small MgO particles were observed on the surface of silicon carbide particles in the original state and in the oxidation state. Quartz particles reacted with magnesium in the matrix to form MgAl2O4 at high temperature. The diffusion mechanism was used to explain the reaction mechanism.
