摘要(Abstract)：

对直径为φ0.8 mm的KSC72A(日本)冷拉态钢丝进行水浴代铅索氏体化处理,用扫描电镜(SEM)和万能材料试验机研究了水浴处理时间对其显微组织和力学性能的影响。结果表明:随着水浴处理时间的延长,钢丝的索氏体团尺寸及片层间距总体呈减小趋势,抗拉强度和伸长率、面缩率随索氏体团尺寸和索氏体片层间距的减小而提高。当以收线速度为50 m/min、水浴槽长度(WT1)为50 cm时,水浴处理工艺为最佳,钢丝的索氏体团尺寸、片层间距分别为2.86μm、82.76 nm,组织细小均匀,抗拉强度可达1266 MPa,显微硬度为340 HV,伸长率为6.4%、收缩率为54.5%,具有良好的综合力学性能,满足钢丝的技术要求,水浴处理可以取代铅浴对钢丝进行索氏体化处理。
