摘　　要：采用原位合成技术制备了碳化钛颗粒增强高锰钢复合材料;采用洛氏硬度计、扫描电镜和金相显微镜探讨了烧结温度和含碳量对该复合材料孔隙度和硬度的影响。结果表明:当烧结温度为1350～1420℃时,该复合材料的孔隙度随烧结温度的升高而减小。当烧结温度超过1420℃,该复合材料的孔隙度随着温度的升高而增大;该复合材料的硬度随温度的变化趋势与孔隙度刚好相反,当烧结温度一定时,该复合材料的孔隙度随碳含量的增加而增大,而其硬度变化与含碳量之间没有明显规律性。TiC reinforced high manganese steel composite was produced by insitu synthesis technique. The effect of sintering temperature and carbon content on the void ration and hardness of the composite was discussed by rockwell hardness tester, scanning electron microscopy （SEM） and optical microscopy. The results show that the void ration of the composite decreases with the sintering temperature increasing when the sintering temperature is 1350-1420℃. The void ratio of the composite increases with the sintering temperature increasing when the sintering temperature is above 1420 ℃. The hardness change of the composite is just the opposite. The void ratio of the composite increases with the carbon content percentage increasing when the sintering temperature is constant, while the hardness change of the composite is irregular.
