| 摘 要： | 采用在普通45#钢的熔炼过程中加入Ti的方法，制备了不同成分的原位TiC／Fe复合材料，并观察分析不同成分TiC／Fe复合材料的显微组织及硬度变化．结果表明：简单的熔铸法可以制备不同体积分数的TiCp／Fe复合材料，复合材料中多数TiC以细小的规则三角形或四边形存在，且随Ti加入量的增加而增多，TiC达到一定含量时，还会形成棱面枝晶状TiC；材料硬度则随TiC含量增加而提高．当材料制备时只添加Ti，则TiC的形成使基体中碳含量减少，从而使基体中的Fe3C减少或消失，其硬度随钛含量的增加而先增后降，同时过量的钛不仅形成缺碳的非计量比TiCx，还形成条状的Fe2Ti金属间化合物．

| Abstract: | During melting process of the No.45 plain carbon steels,In-situ TiC particle-reinforced ferrous matrix composites with different contents were fabricated by adding Ti metal.The microstructure of composites was analyzed,and its performance was measured.The results show that different volume fraction of TiC particle-reinforced ferrous matrix composites can be fabricated by using simple melting-casting method.The shape of the most TiC in composites is fine,regular triangular or quadrilateral.The TiC quantity i... |
