Abstract

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.
