摘　　要：采用原位自生合成法制备了VCp/Fe复合材料。借助光学显微镜以及扫描电镜等,研究了元素V和C对VCp/Fe复合材料组织和性能的影响。结果表明,随着V含量的增加,VCp/Fe复合材料的硬度和冲击韧性得到了明显的提高。分析得出了制备VCp/Fe复合材料的最佳V和C的组合成分为3.5%V,1.0%C。VC reinforced Fe matrix composites have been prepared by in-situ reaction synthesis process. The influences of vanadium and carbon on the microstructure and properties of VCp/Fe composite have been investigated by using optical microscopy and SEM. Results show that with the increasing of vanadium, the hardness and impact toughness were improved heavily. Further analysis show that 3.5%V and 1.0% C are the suitable percentage contents.
