Abstract

The invention discloses a short-process preparation method of a Cu-Cr-Zr alloy strip, comprising the following steps: 1) billet heating: taking a Cu-Cr-Zr alloy casting billet, heating and maintaining the temperature to obtain a high-temperature billet; 2) synchronizing Extrusion solid solution: extrude the high temperature billet, and place the extruded billet in water for water sealing and solution treatment. The short-flow preparation method of the present invention is to heat the Cu-Cr-Zr alloy casting billet for simultaneous extrusion and solid solution, and after the solid solution treatment, the subsequent cold deformation can be directly carried out, which greatly shortens the technological process, reduces the production cost, and improves the The labor efficiency is improved, and the problem of difficult solid solution of the traditional Cu-Cr-Zr alloy strip is overcome; the obtained Cu-Cr-Zr alloy strip has excellent mechanical and electrical properties, and has broad application prospects; this short process preparation The method has the advantages of simple process, convenient operation and low cost, and is suitable for large-scale industrial production.
