摘　　要：本文通过对亚微米级Ａｌ２Ｏ３Ｐ／６０６１Ａｌ复合材料的ＳＥＭ的动态拉伸观察，研究了该材料的微观断裂行为及其与宏观力学性能的关系，定量地描述了亚微米级Ａｌ２Ｏ３Ｐ／６０６１Ａｌ复合材料的断裂过程，并讨论了该种复合材料的断裂机制。In the present study, the fracture behavior of Al 2O 3 P/6061 Al alloy composites and the relationship between fracture process and mechanical properties were studied by SEM dynamic tensile stage. The fracture process of the composites was depicted quantitatively, and the toughness of the composites was discussed.
