[求助] 請幫我翻譯一下這個摘要！

文獻(xiàn) 題目為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.紅色的地方是我不會翻譯的！可以重點(diǎn)翻譯一下！如果翻譯的好，我會追加賞金！

Synthesis and characterization of TiC-reinforced iron-based composites
碳化鈦強(qiáng)化鐵基復(fù)合材料的合成與表征
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.當(dāng)前研究建立了一種利用鋁熱劑反應(yīng)原位一步合成碳化鈦強(qiáng)化鐵基復(fù)合材料的液相加工路徑。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鋁提取廠的一種“廢”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. 通過含硅砂的鋁熱還原得到碳化鈦在鐵基基質(zhì)中的分散體，在碳存在下，分散體含有不同元素如鐵、鈦、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. 還原反應(yīng)放出大量熱，導(dǎo)致了Fe-TiC 復(fù)合材料的自動傳熱高溫合成。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. 基質(zhì)的結(jié)構(gòu)和碳化鈦的體積分?jǐn)?shù)取決于往負(fù)載上添加的碳的數(shù)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.由于碳化鈦粒子的非化學(xué)計量比性質(zhì)，F(xiàn)e-TiC復(fù)合材料的微觀結(jié)構(gòu)在高溫下并不穩(wěn)定。
