Abstract

The invention discloses a rolling method of a high-performance copper-chromium-zirconium alloy plate, and belongs to the technical field of copper alloy processing. The rolling method comprises the following specific implementation steps that (1), solution treatment is carried out; (2), under-aging pretreatment is carried out, specifically, the hardness should be kept at 80%-90% of peak aging hardness, and the electric conductivity should be kept at 80%-90% of peak aging state electric conductivity; (3), rolling treatment is carried out; and (4) peak aging post-treatment is carried out. The advantages of a precipitated phase in the aspects of dislocation proliferation, grain refinement and system energy reduction are fully exerted, and compared with traditional solid solution state rolling and peak aging state rolling, under the same deformation amount, the ductility and the electric conductivity of the high-performance copper-chromium-zirconium alloy plate are kept, and the strength is remarkably improved; compared with a traditional multi-stage rolling and aging process, similar mechanical and conductive properties are obtained under the conditions of smaller deformation, lower energy consumption and shorter process. and the deformation heat treatment method is short in period, low in energy consumption and remarkable in strengthening, and has great application value in industrial production.

Description

Technical field [0001] The present invention belongs to the field of copper alloy processing, and more particularly to a rolling method of a high-performance copper-chrome zirconium alloy sheet. Background technique [0002] Copper and its alloys have excellent conductive properties and higher strength, which is the most widely used conductive material. With the rapid development of electricity, electronics and electromagnetic, advanced equipment represented by high-speed railway contact network, electromagnetic launch system is high and higher. Obviously, pure copper is unable to meet the demand due to its lower strength, and the precipitated copper-chrome zirconium alloy came into being, with high strength, high conductivity, high-resistance, and high-resistance temperature. In recent years, it has been committed to obtaining a structure with high-level error density, ultrafine grain, nano-drawn and low solid copper matrix, in order to achieve higher comprehensive performance. ...
