摘　　要：对Ф10.0 mm螺旋肋钢丝每道次拉拔后的力学性能、稳定处理前后的力学性能和表面残余应力进行研究分析。结果表明:线材经拉拔后的最大力、屈服力、抗拉强度、屈服强度均随应变量的增加呈明显的规律性,断面收缩率及断后伸长率A_(100)规律性不明显。稳定化处理后钢丝的最大力、抗拉强度、屈服力、屈服强度均有明显增大。稳定化处理前周向及轴向残余应力均为拉应力,稳定化处理后周向及轴向残余应力均为压应力。To study mechanical properties of diameter 10.0 mm helical rib wire after cold drawing,mechanical property and residual stress before and after stabilizing annealing.Results show that tensile force,yield force,tensile strength and yield strength of wire rod after drawing changes regularly with increase of strain,while percentage reduction of area and elongation after fracture A_(100) changes irregularly.The maximum force,tensile strength,yield force and yield strength increased significantly after stabilizing annealing.The circumferential and axial residual stress changed from tensile stress to compression stress after stabilizing annealing.
