Effect of Silicon on Microstructure and Mechanical Properties of Nb-V Microalloyed Si-Mn-Cr-Mo Series Bainite Rail Steel
研究了1250 MPa级Nb-V微合金化Si-Mn-Cr-Mo系贝氏体轨钢(/%:0.25 C,0.38-1.56 Si,1.69～1.76 Mn,1.34～1.37 Cr,0.32～0.33 Mo,0.034～0.036 Nb,0.11～0.12 V)硅含量对试验钢显微组织和力学性能的影响。试验结果表明:试验钢热轧后空冷,随着硅含量的增加,试验钢的铁素体+珠光体相变被抑制,室温组织中贝氏体、马氏体含量增加,影响钢的强度和硬度,硅含量由0.38%提高到1.56%时,试验钢的屈服强度由846 MPa增至903 MPa,抗拉强度由1 280 MPa增至1 355 MPa,HBW硬度值由353增至4...
