选用国产Al_2O_3纤维与英国Saffil纤维怍为增强体,工业纯Al作为基体制成复合材料。在扫描电镜下,进行了微观断裂过程动态观察,并结合强度测定及断口分析探讨了不同情况下的断裂机理。
Selection of domestic Al_2O_3 fiber and the United Kingdom Saffil fiber 怍 as reinforcement, industrial pure Al as a matrix made of composite materials. Under the scanning electron microscope, the dynamic observation of microscopic fracture process was carried out, and the fracture mechanism under different conditions was discussed in combination with the strength measurement and fracture analysis.
