摘要

作品中介绍了铜线加工的新技术。该技术包括在旋转的等道阶梯模具中使线材变形，然后进行拉伸。模具绕线材轴线旋转，并在模具内通过等通道角拉丝和扭曲产生应力。实验室实验结果表明，变形后可获得高角度晶界含量较高的超细晶粒分级微观结构。与未变形铜线相比，变形铜线的拉伸强度从 302 兆帕增加到 635 兆帕，屈服强度从 196 兆帕增加到 406 兆帕。

Analysis of the twisting effect in an equal-channel stepped die and drawing on copper wire mechanical properties

New technology is presented in the work for copper wire processing. This technology consists of deforming wire in a rotating equal-channel stepped die and subsequent drawing. The die rotates around the axis of the wire and creates stress due to equal-channel angular broaching and twisting within the die. Results of a laboratory experiment show that after deformation an ultrafine grained graded microstructure with a high content of high-angle grain boundaries is obtained. Tensile strength of deformed copper wire in comparison with undeformed wire increases from 302 to 635 MPa, and yield strength increases from 196 to 406 MPa.
