Increasing the ductility of ultrafine-grained copper alloy by introducing fine precipitates
Access this Article
We fabricated ultrafine-grained (UFG) Cu–Cr–Zr alloy including fine second-phase particles via an accumulative roll-bondingprocess and subsequent aging treatment. The nanosized precipitates dispersed within the UFG matrix significantly enhanced strainhardening, resulting in the simultaneous improvement of uniform elongation and tensile strength.
