摘　　要：石墨烯具有高强度、高韧性、低密度和耐高温的优异性能,是一种理想的复合材料增强体。采用性能优异的石墨烯代替贵重金属元素,通过常温下单向压制结合高温烧结的粉末冶金法将石墨烯粉末均匀地分散在铁基材料中,分别制备出了Fe-C、GNSs/Fe和GNSs/Fe-C三组材料,探究该工艺下不同含量的石墨烯对铁基复合材料性能的影响。Graphene is an ideal composite with high strength,high toughness,low density and high temperature resistance. The graphene can be used instead of precious metal elements. Fe-C,GNSs/Fe and GNSs/Fe-C are prepared by powder metallurgy method through ways of uniaxial pressing at normal temperature combined with high temperature sintering. The effects of different contents of graphene on the performance of iron-base composites are investigated.
