摘　　要：综述了现今大塑性变形技术的工艺方法,分析了冷拉珠光体钢丝的研究方法、加工硬化及组织性能演变,重点研究了剧烈冷拉塑性变形珠光体钢丝的加工硬化机制、渗碳体的强制溶解机制及应变时效对其性能产生的影响。The current several severe plastic deformation techniques are reviewed In this paper. The investigation methods, work-hardening, and evolution of microstructure and mechanial properties of cold drawing pearlitic steel wires are analyzed. The mechanism of work-hardening, the cementitle dissolution in severely cold drawing plastic deformation pearlitic steel wire, and the effect of strain ageing are studied mostly.
