摘要
通过液态原位反应合成制备MgO/Mg2Si增强Mg-Li基复合材料,利用TEM对增强相形态及界面结构进行了观察。实验结果表明,复合材料中增强粒子与基体界面结合良好,无反应物生成。确定了增强粒子与基体的界面取向关系,MgO与基体α相的晶体学关系为[100]MgO‖[4043]α,(011)MgO‖(1210)α;Mg2Si与基体β相的晶体学关系为[310]Mg2Si‖[411]β,(131)Mg2Si‖(001)β。
Mg-Li composites reinforced by MgO/Mg2Si particulates was prepared by reaction synthesis in liquid and TEM was used to analyze the form of the reinforcing particulatcs and interface strucrure.The experimcntal results show that there are no any apparent reactant on the interface.The interface microstructure of the composites indicates that there exists the following crystallization relationship between particles and matrix：[100]MgO//[40（￣4）3]α,（011）MgO//（（￣1）2（￣1）0）α amd [310]Mg2Si//[411]β,（1（￣3）（￣1））Mg2Si//（001）β,respectively.
