摘　　要：采用激光宽带扫描对CrWMn钢进行了相变强韧化处理,对硬化层的显微组织和硬度进行了分析与测试。结果表明,对CrWMn钢激光扫描搭接量的选择12%～16%较好,距表面0.1～0.3 mm处硬度平均可达720 HV。The microstructure and microhardness of hardened layer of CrWMn steel which was hardening and toughing treated by laser broadband scanning were anslyzed and tested. The results show that the laser scanning lap-amount＇s choice of CrWMn steel is about 12% - 16% ,the hardened layer average hardness under surface 0. 1 -0. 3 mm could be 720 HV.
