以成本低廉的钛铁矿经还原后得到的含 Fe的碳氮化钛(TiCN)复合粉为增强相原料制备了铁基复合材料。结合金相组织观察、SEM和 EDS 分析以及力学性能测试研究了复合粉添加量对铁基复合材料组织和性能的影响，进一步研究了 Mo 的添加对铁基复合材料组织与性能的影响。结果表明，复合粉的添加量为40％(质量分数)时制备的复合材料综合性能较好。复合材料中添加少量的Mo 后增强相颗粒的平均尺寸减小，综合性能得到了提高。

In this paper,the iron matrix composites were prepared using titanium carbonitride composite powder as the reinforcement which was obtained via carbothermic reduction of ilmenite with low cost.The effect of composite powder contents on the microstructure and properties of iron matrix composites was studied with metallographic observation,SEM,EDS and mechanical properties testing.The effect of Mo addition on the mi-crostructure and properties of iron matrix composites was further studied.It was shown that the iron matrix composites had better performance when the content of composite powder was 40wt%.With small amount of Mo addition,the average particle size of enhancement decreased and mechanical properties were improved.
