摘　　要：对Cu、Ni、Sn三种元素在TiCP/Fe复合材料中的作用效果进行了分析对比研究。结果表明,三种元素对抑制或消除石墨有害相,提高材料综合力学性能等方面都有较显著的效果,但各元素作用效果有一定的差别。在减少或抑制片状石墨有害相方面,Cu元素和Ni元素更为显著;在提高TiC增强颗粒含量和改善TiC增强颗粒形貌尺寸方面,Ni元素和Cu元素具有明显优势,Sn元素次之;在提高材料硬度方面,Sn元素具有明显优势,Cu元素和Ni元素次之。The effects of Cu, Ni, Sn three kinds of elements in TiCdFe composite were analyzed. The results show that the three elements are harmful to the suppression or elimination of graphite phase. They can improve overall mechanical properties of materials and other aspects than significant effect, but effect of various elements is somewhat different. Flake graphite to reduce or suppress harmful with respect to elements of Cu and Ni elements are more significant. Improve the content of TiC particles in enhancing and improving the particle morphology of TiC increase in size, Ni and Cu elements have obvious advantages, Sn element followed. Increase in hardness in the Sn element has obvious advantages, Cu and Ni elements, followed by elements.
