摘　　要：用脉冲Nd:YAG固体激光机对718进行淬火,详细描述了激光机的电流、脉宽、频率和扫描速度对718模具钢淬火效果的影响。从淬火后的硬度、表面质量和淬透深度三个方面入手,结合脉冲激光本身的特点,优化工艺参数,并对其原因进行解释。Nd：YAG impulse-action laser machine was used to quenching 718 die steel. The effects of the laser machine＇s impulse electric current, impulse width, frequency and scanning speed on the quenching results were studied. From the aspects of hardness after quenching, surface quality and the depth of quenching ability of 718 die steel, the optimal process parameters were obtained, the reasons for the above affect were explained.
