摘要

This study investigated the quenching deformation mechanism and process optimization of the 17Cr2Ni2Mo gear shaft through simulations and experiments. A heat treatment model, including temperature, stress–strain, and microstructure fields, was established to explore deformation during quenching mechanisms. The effects of quenching temperature, stirring speed, and holding time on C-ring deformation were analyzed. Orthogonal experiments verified the simulation results, showing a consistent deformation trend. The deformation increases with the increase of quenching temperature, the extension of holding time, and the acceleration of stirring speed, while the uneven oil quality under static conditions will exacerbate the deformation. The optimized quenching process effectively reduced deformation, verified the accuracy of simulation results, and provided a theoretical basis and scheme guidance for optimizing the quenching parameters of 17Cr2Ni2Mo material.
