| 摘 要： | 综合搅拌铸造法和原位反应制备了Al2O3颗粒增强Al-4Mg基复合材料，并对制备的Al-4Mg基复合材料进行了透射电镜(TEM)观察分析，发现Al2O3／Al之间不存在固定的位向关系，但存在如下优先的位向关系：(1210)Al2O3∥(111)Al，1012]Al2O3∥112]Al，2021]Al2O3∥101]Al．

| Abstract: | Al2O3 particles, in situ decomposed from Al2(SO4)3, reinforced Al-4Mg matrix composites were made through stir casting. Al2O3/Al interface in the Al-4Mg matrix composites was studied by transmission electron microscopy (TEM). The measurements of crystallographic orientation relationship between Al2O3 and Al at Al2O3/Al interface show that no fixed and unique orientation relationship existed, though the following preferential ones were observed: (1210)Al2O3//(111)Al> 1012]Al2O3 // 112]A1, 2021]Al2O3 // 101]Al. |
