| 摘 要： | 研究了原位自生 10 %TiC/Fe(体积分数 )复合材料显微组织及W对该复合材料的影响作用。结果表明 ,在原位合成的 10 %TiC/Fe复合材料中 ,TiC相是唯一的第二相 ,它呈块状和条状两种形态。在以 5 0 %W (摩尔分数 )替代 5 0 %Ti(摩尔分数 )的 10 % (Ti0 .5W 0 .5)C/Fe(体积分数 )复合材料中 ,形成了 (TiW )C相 ,它是唯一的第二相 ,其形态基本上是呈块状 ,而条状较少。在以 6 0 %W(摩尔分数 )替代 6 0 %Ti(摩尔分数 )的 10 % (Ti0 .4 W0 .6)C/Fe(体积分数 )复合材料中 ,除形成 (TiW )C相外 ,还形成了富W的Fe6W6C相 ,这两种几乎都为条状。

| Abstract: | The effect of substitution of titanium with tungsten on microstructure of in situ synthesized 10%TiC/Fe (volume fraction) composite was investigated. The results show that in the 10%TiC/Fe, TiC is only one second phase and it appears in two kinds of morphologies, i.e. block like and rod like. In 10%(Ti 0.5 W 0.5 )C/Fe (volume fraction) in which 50%Ti (mole fraction) is substituted by W, as only second phase (TiW)C is formed and most of it is block like and few rod like. In 10%(Ti 0.4 W 0.6 )C/Fe (volume fraction) in which 60%Ti (mole fraction) is substituted by W, besides (TiW)C, a tungsten rich phase, Fe 6W 6C, is formed and almost all the phases are rod like. |
