| 摘 要： | 系统地研究了化学成分对原位ＴｉＣｐ／Ｆｅ复合材料组织和性能的影响，并确定了该材料的最佳化学成分。结果表明：Ｔｉ是影响复合材料组织中ＴｉＣ颗粒形核率的关键因素，而Ｃ主要影响组织中ＴｉＣ颗粒的尺寸；在合金熔体中，加入一定量的Ｓｉ有利于ＴｉＣ颗粒的形成，而Ｍｎ主要用来细化珠光体基体。

| Abstract: | The effects of chemical composition on microstructures and mechanical properties of insitu TiCp/Fe composites have been studied systematically, and the optimum chemical composition of this composite has also been determined. The results showed that Ti is the key factor affecting the nucleating rate of TiC particulates, and C mainly affects the sizes of TiC particulates in the composite microstructures. Adding proper Si content to alloy melt is favourable to form TiC particulates, and Mn is mainly used to refine pearlite matrix. |
