具有良好切削加工性能的贝氏体铁素体非调质钢

Non-Quenched and Tempered Bainitic-Ferritic Steel With Good Machinability

在实验室制备了非调质钢B12Mn2VB,检验了该钢的组织及力学性能,研究了该钢的切削加工性能,在THERMECMASTER-Z热模拟试验机上测定了该钢的连续冷却转变曲线。结果表明,该钢的综合力学性能比调质40Cr钢好,切削加工性能比45钢优越。

Non-quenched and tempered steel B12Mn2VB was manufactured in laboratory.The microstructure and mechanical properties were determined,the machinability was researched,and the continuous cooling process were simulated on THERMECMASTER-Z thermomechanical simulator.The results indicate that the mechanical properties are better than those of quenched and tempered steel 40Cr,and the machinability is much better than that of 45 steel.
