文献 题目为Synthesis and characterization of TiC-reinforced iron-based composites 摘要：The present investigation establishes a liquid processing route where thermit based reactions have been used to synthesize in-situ TiC-reinforced Fe-based composites in a single step.The main raw material used is siliceous sand,which is a“waste”product of aluminum extraction plants.A dispersion of TiC in Fe-based matrix has been obtained by aluminothermic reduction of siliceous sand,containing oxides of different elements like iron,titanium,silicon etc.,in the presence of carbon.The reduction is highly exothermic in nature and leads to a self-propagating high-temperature synthesis(SHS)of the Fe-TiC composites.The matrix structure and volume fraction of TiC of the composites have been found to depend upon the amount of carbon added in the charge.It has been found that microstructures of Fe-TiC composites are not stable at high temperature due to the nonstoichiometric nature of TiC particles.红色的地方是我不会翻译的！可以重点翻译一下！如果翻译的好，我会追加赏金！ [ Last edited by 工程小硕 on 2011-5-23 at 20:40 ] |

Synthesis and characterization of TiC-reinforced iron-based composites 碳化钛强化铁基复合材料的合成与表征 摘要：The present investigation establishes a liquid processing route where thermit based reactions have been used to synthesize in-situ TiC-reinforced Fe-based composites in a single step.当前研究建立了一种利用铝热剂反应原位一步合成碳化钛强化铁基复合材料的液相加工路径。The main raw material used is siliceous sand, which is a“waste”product of aluminum extraction plants. 主要用到的原材料是铝提取厂的一种“废”物料含硅砂。A dispersion of TiC in Fe-based matrix has been obtained by aluminothermic reduction of siliceous sand,containing oxides of different elements like iron,titanium,silicon etc.,in the presence of carbon. 通过含硅砂的铝热还原得到碳化钛在铁基基质中的分散体，在碳存在下，分散体含有不同元素如铁、钛、硅等的氧化物。The reduction is highly exothermic in nature and leads to a self-propagating high-temperature synthesis(SHS)of the Fe-TiC composites. 还原反应放出大量热，导致了Fe-TiC 复合材料的自动传热高温合成。The matrix structure and volume fraction of TiC of the composites have been found to depend upon the amount of carbon added in the charge. 基质的结构和碳化钛的体积分数取决于往负载上添加的碳的数量。It has been found that microstructures of Fe-TiC composites are not stable at high temperature due to the nonstoichiometric nature of TiC particles.由于碳化钛粒子的非化学计量比性质，Fe-TiC复合材料的微观结构在高温下并不稳定。 |
