针对60Si2MnA弹簧钢盘条在拉拔过程中出现的脆性断裂问题，利用扫描电镜、光学显微镜等手段对断裂试样的宏观缺陷、断口形貌、金相组织、脱碳、偏析及夹杂等进行了系统检测，分析了脆断产生的原因，并提出了相应的改进措施，提高了弹簧钢质量。

Aiming at the brittle fracture occurred during the drawing of wire rod of 60Si2MnA steel, systematic inspection was made on the macroscopic defect, fracture morphology, microstructure, decarburization, segregation and inclusion of the failure sample by means of scanning electron microscope and optical microscope to analyze the cause of brittle fracture. The authors put forward relevant improvement measures, which improved the quality of spring steel.
