1.
The oil-tempered spring steel wire for suspension spring happen to brittle fracture in production,storage and transporting.
悬架簧用油淬火回火弹簧钢丝在生产、运输和贮存过程中会发生脆断 ,通过对脆断钢丝进行理化分析、金相检验和断口形貌的电子显微镜扫描分析 ,认为造成钢丝脆性断裂的直接原因是钢丝表面缺陷 (如表面裂纹、夹杂、机械碰伤等 ) ,这些缺陷在弹性弯曲和热处理残余应力的共同作用下 ,导致了裂纹的萌生、扩展 ,最终导致材料脆断 ,断口形貌的主要特征是沿晶断裂。
