Deformation Behavior of Gear Steel During Carburizing Heat Treatment
The deformation behavior, carburized depth and microstructure of the gear steel with different quenching method were studied. The results show that the deformation rate of the gear steel gradually rise with air quenching, water quenching and oil quenching. The depth of hardening layer after oil quenching is deeper than that after air quenching. After oil quenching, the martensite can be found in the microstructure of gear steel, and it is helpful to improve the microhardness of the gear steel.
