| Abstract: | Contact wire of CuCr1 alloy was produced by solid solution-continuous extrusion-aging-rolling-drawing process and solid solution- continuous extrusion-rolling-aging-drawing process, and the microstructure and properties of the CuCr1 alloy in different states were tested and analyzed, respectively. The results show that after aging treatment, the performance of continuous-extruded CuCr1 alloy is better than rolled. The microstructure of continuous extruded CuCr1 alloy is banded deformation structure with a small amount of recovery structure. The microstructure of rolled CuCr1 alloy is deformed grains and Cr phase distributed along the banded grain boundary, and microstructure of the aged CuCr1 alloy is mainly recrystallized structure. After solution treating, continuous extruding, aging, rolling and drawing, the tensile strength of the contact wire reaches 489 MPa, conductivity reaches 79.47%IACS, and its performance is better than that produced by the solid solution-continuous extrusion-rolling-aging-drawing process. |
