| 摘 要： | 研究了Si，Mn合金元素加入量对自生TiC颗粒增强的钢基复合材料的组织和性能的影响．结果表明，在自生TiC颗粒增强钢基复合材料中，随着Si，Mn合金化元素的升高，复合材料基体组织将经历从单相珠光体到珠光体马氏体，再到单相马氏体的变化过程．相应地，复合材料铸态硬度从单相珠光体的HRC43．1变化到单相马氏体的HRC55．Si，Mn合金化元素的含量对热处理态复合材料的硬度也有明显影响，但对冲击韧性影响不大。

| Abstract: | The effect of Si, Mn alloy elements on the microstructure and mechanical properties of in-situ TiC particles reinforced steel matrix composites was studied. The result showed that with the increas of Si, Mn contents, the microstructure of the composites varied from single-phase pearlite to the mixture of pearlite and martensite, finally to single-phase martensite; accordingly, the hardness of the composites at cast changed from HRC43.1 to HRC55. Also, the Si, Mn contents influenced a little the hardness of the heat-treated composites, but not their impact toughness. |
