本文根据激光与金属材料的相互作用，从建立一般热传导方程出发；导出了激光热处理过程的温度场方程，讨论了数值模拟激光热处理时的各个参数取值，并用此方程对热处理过程进行了数值模拟，得出与实验吻合较好的结果
Based on the interaction between laser and metal material, a general heat conduction equation is established. The temperature field equation of laser heat treatment is deduced. The parameters of laser heat treatment are discussed. The heat treatment process is numerically simulated , We get the better agreement with the experiment
