| 摘 要： | 本文研究了ZrC颗粒加入量对低碳微合金钢组织和力学性能的影响。对试验钢进行了各种力学性能的测试,并用金相显微镜和TEM观察了试验钢的微观组织,用SEM观察了ZrC颗粒的分布状态及拉伸断口形貌。结果表明,加入ZrC颗粒后,试验钢的晶粒都得到了一定程度的细化,当加入ZrC颗粒体积含量为1.1%时,晶粒被细化到5.5μm,此时试验钢的抗拉强度、屈服强度、伸长率、冲击韧性和维氏硬度分别达到635MPa、517.5MPa、20.66%、215.0J/cm2和214 Hv5,获得了最佳综合力学性能;添加ZrC颗粒后,试验钢的组织仍为铁素体,拉伸断口仍为韧窝状;轧制态试验钢中ZrC颗粒分布较为均匀。
