摘　　要：对高强度镀锌钢丝的扭转性能和拉拔钢丝的力学性能及微观组织进行研究。力学性能分析表明:扭转性能好的拉拔钢丝的强度和塑性相比扭转性能差的拉拔钢丝无较大差别,然而扭转性能好的拉拔钢丝表面显微硬度比扭转性能差的拉拔钢丝低,波动相对也较平稳。微观组织研究表明:扭转性能差的拉拔钢丝表层组织无半脱碳是其表面硬度较高的主要原因。In this paper,the torsion properties of high strength galvanized steel wire and the mechanical proper-ties and microstructure of the drawing steel wire were studied.The mechanical properties analysis shows that there is no difference in both of strength and ductility between drawing steel wire with good or poor torsion per-formance.However,the surface hardness value of drawing steel wire with good torsion performance is lower than that of drawing steel wire with poor torsion performance?and the volatility are also relatively more stable.Microstructure research shows that the microstructure of surface layer without semi-decarburization or non-uni-form semi-decarburization of the drawing wire with poor torsion performance is the main reason for the high surface hardness.
