摘　　要：采用原位自生合成法制备了TiCp/Fe复合材料。借助光学显微镜以及扫描电镜等,探讨了Cu对TiCp/Fe复合材料组织和性能的影响。结果表明,随着Cu含量的增加,TiCp/Fe复合材料组织中片状石墨有害相得到了有效地抑制,且其综合力学性能得到了提高。分析得出制备TiCp/Fe复合材料的最佳Cu含量约为1.5%。TiC reinforced Fe matrix composites were prepared by in-situ synthesis process.Influences of copper on the microstructure and proprties of TiCp/Fe composites were investigated by using optical microscopy and SEM（scanning electron microscopy）.The results show that with the increase of copper,the lamellar graphite in the TiCp/Fe is suppressed effectively,and the hardness,tensile strength and impact toughness of the composites are improved obviously.1.5% copper addition is suitable.
