摘要: 采用扫描电子显微镜对粉末冶金法制备的SiCp/7075Al复合材料的拉伸断口及其附近区域的纵向显微组织进行了分析,并对该材料的断裂过程进行了动态原位观察。为了揭示SiCp/7075Al复合材料的断裂特性,建立了SiCp/7075Al复合材料的拉伸断裂模型。Abstract: The paper has analysed the tensile fissure of SiC/7075A1 P/M composite materials and longitudinal structure in the area around the fissure by using SEM. Dynamic in situ observation for the fracture process of the materials has been put forward fracture mould of SiC/7075A1 composite materials have been established with the purpose of disclosure of the fracture behavior of SiC/7075A1 composite materials.
