【摘要】 研究了制备铸造原位（ＩｎＳｉｔｕ）ＴｉＣｐ／Ｆｅ复合材料的工艺方法，分析了所得材料的组织。结果表明：在ＦｅＴｉＣ系合金熔体中，Ｔｉ与Ｃ易发生化学反应生成ＴｉＣ颗粒，该ＴｉＣ颗粒可成为奥氏体形核和生长的核心，在此基础上可制得具有较理想组织的铸造原位ＴｉＣｐ／Ｆｅ复合材料。更多还原

【Abstract】 Abstract The preparing technique of casting in situ TiCp/Fe composite was investigated and the microstructure of prepared composites was also analysed.The results showed that,in the FeTiC alloy melt,Ti can combine easily with C to form TiC particulates,which acts as a nucleus of austenite grain growth,thus preparing in situ TiCp/Fe composites have better microstructures.更多还原
