纤维增强金属基复合材料的力学性能在很大程度上取决于增强纤维与金属基体之间的界面状况,适中的界面结合可使材料具有较为理想的性能。对复合材料的界面虽已进行了不少研究,但应用透射电镜方法却还只是开始,本文用透射电镜观察了碳—铝复合材料的界面,分析了界面的相组成,并讨论了界面状态对复合材料性能的影响。
The mechanical properties of fiber reinforced metal matrix composites depend largely on the interfacial conditions between the reinforcing fibers and the metal matrix. The moderate interfacial bonding can make the material have better properties. Although many studies have been made on the interface of the composite material, the application of TEM has just begun. The interface of the carbon-aluminum composite material is observed by transmission electron microscopy, the phase composition of the interface is analyzed, and the interface state pairs Effect of composite material properties.
