According to the characteristics and complexity of the laser quenching process, a finite element method is proposed to calculate the heat transfer mathematical model of the temperature field and the distribution of the microstructure in the laser quenching process. In the calculation, the linear regression of the thermophysical properties with the temperature is carried out ; Laser quenching is a category of rapid heating, austenitizing the corresponding increase. Phase change latent heat is based on the amount of phase change in the form of temperature rise, temperature drop to be processed. Taking MoCu ductile iron as an example, the temperature field and microstructure distribution under different laser processing parameters were calculated and experimentally verified.
