文章编号:1004-0609(2009)10-1795-07 SiC颗粒对SiCp/2009Al复合材料疲劳短裂纹扩展的影响 邹利华1,樊建中2,左 涛1,张 琪1,魏少华1 (北京有色金属研究总院 国家有色金属复合材料工程技术研究中心,北京 100088) 摘 要:采用粉末冶金法制备15%(体积分数)SiCp/2009Al复合材料,研究该材料的微观组织,力学性能,高周疲劳性能以及疲劳断口形貌.结果表明:在SiCp/2009Al复合材料的疲劳短裂纹扩展阶段,SiC颗粒及其表面包覆的2009Al薄层在裂纹扩展面上形成"丘陵"状形貌,使疲劳断口的粗糙度增大,裂纹的闭合效应也随之增大；同时"丘陵"状形貌可以引发疲劳裂纹扩展路径偏析,使裂纹扩展的有效驱动力减小并使裂纹扩展路径增加；上述裂纹迟滞效应使SiCp/2009Al复合材料在短裂纹扩展阶段具有较高......
