摘要：

The multi-field coupling instantaneous evolution law of laser quenching process was quantitatively revealed, then the significance analysis of 40Cr laser quenching process parameters was carried out. Based on the calculation of phase diagram (CALPHAD) method, the temperature changes physical properties of the material were calculated, and the coupled numerical model of 40Cr gear steel during laser quenching was established. Numerical calculations of the transient temperature, phase transition, and stress distribution of 40Cr laser quenching revealed the interaction mechanism between phase transition behavior and plastic stress. Axio Vert. A1 microscope, scanning electron microscope (SEM), super depth of field 3D microscope, and microhardness tester were used for analysis. The significant effects of laser radius, laser power, and scanning speed on quenching quality were analyzed based on orthogonal experiments. The results showed that the significant process parameters affecting the maximum temperature and phase transformation depth were spot diameter, scanning speed and laser power. The distribution of residual stress was “hump”,and the significant process parameters affecting the residual tensile stress were spot diameter, laser power and scanning speed. This research provides an essential theoretical basis for effectively controlling residual quenching stress and optimizing quenching process parameters. © 2024 Beijing University of Aeronautics and Astronautics (BUAA).
