| 摘 要： | 通过马氏体转变动力学和碳浓度的扩散系数有限元模型,对16Cr3NiWMoVNbE齿轮钢C型环进行真空低压渗碳淬火的温度场、浓度场、组织场、以及应力场的研究。结果表明,渗碳淬火后,得到碳浓度分布,可以很好地解释表层部分的最终马氏体分布情况,为预测齿轮钢渗碳淬火后碳浓度分布和马氏体分布提供了可靠依据。

| Abstract: | Temperature field, concentration field, microstructure field and stress field of vacuumlow pressure carburizing and quenching of 16Cr3NiWMoVNbE gear steel C-ring were studied by using the finite element model of martensitic transformation kinetics and carbon concentration diffusion coefficient. The results show that the carbon concentration distribution obtained after carburizing quenching can well explain the final martensite distribution in the surface layer. A reliable basis is provided for predicting the carbon concentration distribution and martensite distribution of the gear steel after carburization and quenching. |
