| 摘 要： | 利用Gleeble-1500热模拟机对不同Nb含量的TRIP钢的热轧过程进行了热模拟实验.研究了Nb含量对TRIP钢组织和性能的影响.实验结果表明：Nb的加入使得实验钢的组织得到细化,贝氏体量增多;增加Nb含量,残余奥氏体量和残余奥氏体含碳量有所降低,宏观维氏硬度值增加;Nb的质量分数为0.014%时,残余奥氏体量为19.2%、残余奥氏体含碳量为1.422%、宏观维氏硬度为258HV和抗拉强度为851 MPa.

| Abstract: | The hot deformation process of low silicon TRIP steels with different Nb content was simulated by Gleebe-1500 hot mechanical simulator.The effects of niobium content on microstructures and properties of TRIP steel were studied.The results showed that microstructures of experimental steels were refined and bainite content was increased with the addition of Nb.If Nb content was added,retained austenite fraction and carbon contents of retained austenite decreased,and Vickers hardness and tensile strength increased.When Nb content was 0.014(mass,%),retained austenite fraction was 19.2%,carbon contents of retained austenite was 1.422%,Vickers hardness was 258HV and tensile strength was 851MPa,respectively. |
