摘要
为了在大气条件下利用 Fe- Ti- C熔体中 Ti C的合成反应制备原位 (in situ) Ti CP/Fe复合材料 ,研究了三种覆盖剂对熔体中 Ti元素氧化烧损率的影响 ,并分析了所得复合材料的组织和性能。结果表明 :采用所开发的混合盐型覆盖剂能在大气条件下制备出原位 Ti CP/Fe复合材料 ,且原位合成的 Ti C颗粒尺寸细小、分布均匀 ,从而使制备的复合材料特别是经淬火处理后的复合材料具有较高的力学性能。
In order to fabricate in situ TiC P/Fe composites under air condition by the synthesis of TiC in Fe Ti C melt, the effects of three kinds of covering agents on the oxidization ratio of element Ti in the melt were studied, and the microstructures and mechanical properties of the prepared composites were also analyzed. The results show that the developed mixed salts type covering agent can be used to produce in situ TiC P/Fe composites under air condition, in which the TiC particles exhibit finer size and homogeneous distribution in the matrix structure, resulting in the composites, especially the quenched composites, to have higher properties.
