从相变理论和热弹塑性理论出发,并结合激光淬火实验资料,建立了考虑相变过程、温度场和变物性系数的非线性耦合热传导方程;建立了相变组织与材料性能的数值计算模型。然后用有限元法进行了温度场、相变组织分布、材料性能的数值模拟。通过计算与试验结果的比较,计算结果令人满意。在获得激光淬火最佳工艺参数、预测材料性能方面有一定的实际应用价值和理论研究价值。

From the theory of phase transformation and thermal elastoplastic, and based on experimental data of laser quenching, a non linear coupling heat conduction equation considering phase transformation, temperature field and variable physical properties can be estabilished. A model of the relationship between the phase transformation producers and the material properties is put forward which is resolved by means of the Finite Element Method (F.E.M.). Comparing the calculated results with those of experiments, satisfying agreement is found. It might be valuable for some practical applications and for the development of theory.
